Problem with "implementation.osgi" reference
Hello
I want to use an osgi service as a SCA component. But I can not access to
their methods from other Component. I mean I have created a wired
instance to the Osgi Service ($Proxy25). It is not "null" but I can not
invoke to one method because an error is happening
--->Unable to create SCA binding invoker for local target
SensorNetworkManagementComponent reference prueba (bindingURI=null
operation=sayHello)
This is my composite file. I want to have to two components. The first had
a reference to the second and it is normal "implementation.java". The
second is the SCA component that is representing to the Osgi Service that
I want to recover. This Osgi Service was registered in the Osgi registry
by Activator class in "RegistroService" bundle.
<sca:component name="SensorNetworkManagementComponent">
<sca:implementation.java
class="es.amivital.sensornetworkmanagement.sca.SensorNetworkManagementServiceImpl"/>
<sca:service name="SensorNetworkManagementService">
<sca:binding.ws uri="
http://localhost:8085/SensorNetworkManagementComponent"/>
</sca:service>
<sca:reference name="prueba" target="PruebaComponent"/>
</sca:component>
<sca:component name="Prueba">
<sca:implementation.osgi xmlns="
http://tuscany.apache.org/xmlns/sca/1.0"
bundleSymbolicName="RegistroService"
bundleVersion="1.0.0">
<sca:properties service="prueba.PruebaImpl">
</sca:properties>
</sca:implementation.osgi>
</sca:component>
***The Java code--> The first component.
public class SensorNetworkManagementServiceImpl implements
SensorNetworkManagementService {
private Prueba prueba;
public Prueba getPrueba() {
return prueba;
}
@Reference
public void setPrueba(Prueba prueba) {
this.prueba = prueba;
}
}
**Java code --> The second component. It is another bundle that is
registering one simple Osgi Service. The interface was
public interface Prueba {
public abstract String sayHello();
}
This instance (prueba) is not null when an outside client invoke to the
first component. But if I invoke to one method of this interface, for
example "prueba.sayHello" I obtained the previous error.
I have read something about anottations like @AllowsPassByReference
or @Scope, but I don´t know if they are neccesary .

Yes it is strange because using java code in order to register SCA node was
working. The source code of ContributionProcessor is
// Create contribution model
Contribution contribution =
contributionFactory.createContribution();
contribution.setURI(contributionURI.toString());
contribution.setLocation(contributionURL.toString());
ModelResolver modelResolver = new
ExtensibleModelResolver(contribution, modelResolvers, modelFactories);
contribution.setModelResolver(modelResolver);
contribution.setUnresolved(true);
// Create a contribution scanner
ContributionScanner scanner =
scanners.getContributionScanner(contributionURL.getProtocol());
if (scanner == null) {
if ("file".equals(contributionURL.getProtocol()) && new
File(contributionURL.getFile()).isDirectory()) {
scanner = new DirectoryContributionScanner();
} else {
scanner = new JarContributionScanner();
}
}
* // Scan the contribution and list the artifacts contai**ned in it*
List<Artifact> artifacts = contribution.getArtifacts();
boolean contributionMetadata = false;
List<String> artifactURIs = scanner.getArtifacts(contributionURL);
for (String artifactURI: artifactURIs) {
*URL artifactURL = scanner.getArtifactURL(contributionURL,
artifactURI); --> This returns null*
// Add the deployed artifact model to the contribution
Artifact artifact = this.contributionFactory.createArtifact();
artifact.setURI(artifactURI);
* artifact.setLocation(artifactURL.toString()); --> This is the
line 131*
artifacts.add(artifact);
modelResolver.addModel(artifact);
artifactURL is null because of java.lang.NullPointerException is thrown in
the line 131. I guess it is looking for something about "contribution" and
it can not recover some file correctly. I am sure there is something about
contribution when I was using the java code that I don´t have when I don´t
use this code.
I remember you the java code I used
* *
**try {
//Registrado el servicio SensorNetworkManagement en el dominio SCA
NodeFactory factory = NodeFactory.newInstance();
String url =
ContributionLocationHelper.getContributionLocation(getClass());
Contribution contrib = new Contribution("c1", url);
node = factory.createNode("OSGI-INF/sca/bundle.composite",
contrib);
node.start();
} catch (Throwable e) {
e.printStackTrace();
}

Subject: Re: Fwd: Problem with "implementation.osgi" reference
Ok.
I have checked and I don´t need to write code in order to register SCA node.
Tuscany is trying to register the node with both options
* With "SCA-Composite: true" in the manifest.mf
<rfeng>The value should be a path to the composite file within the bundle</rfeng>
* Without SCA-Composite header but with a OSGI-INF/sca directory.
The second option has a problem using Eclipse. I have seen the source code of NodeManager.java and "isSCABundle" method. bundle.findEntries("OSGI-INF/sca", "*", false) is not working correctly in Eclipse because tries to find these files in /OSGI-INF/sca but they are really in /src/main/resources/OSGI-INF/sca. When I pack the bundle into a jar I have the right structure. But it is not important. I have copied this structure into the root of my Eclipse project.
<rfeng>Good catch.</rfeng>
I have a new error with both options. Tuscany recognizes the bundle as SCA bundle but

When I was using code in order to register the node it was working Ok. I think I need something more. What is sca-contribution.xml. Do I need this file? Where should it be ? I don´t know why "Could not load resource META-INF/maven/es.amivital.calculatorservice2/CalculatorService3/pom.properties" if this file it is from maven and it is not from Tuscany
Thank you very much for your help

You don't have to write the code to start the Node. The node-impl-osgi bundle is watching the SCA enabled OSGi bundles and it will start the Node when the bundle is started.

Sorry I forgot one question.
I am using this code in order to register CalculatorService as SCA service.
try {
//Registrado el servicio SensorNetworkManagement en el dominio SCA
NodeFactory factory = NodeFactory.newInstance();
String url = ContributionLocationHelper.getContributionLocation(getClass());
Contribution contrib = new Contribution("c1", url);
node = factory.createNode("OSGI-INF/sca/bundle.composite", contrib);
node.start();
} catch (Throwable e) {

}
Is it neccesary this??? Can I put composite and component type in "OSGI-INF/sca" directory only? I mean have I to write this code? Does Tuscany read these files automatically?
Does TestService need this code too?
Thank you very much.

So, I have to attach two files (componentType and composite) to my two different bundles (TestService and Calculator) and model it as "implementation.osgi". I have TestService in a bundle I will add these two file and I will design as "implementation.osgi" .
But Calculator Service (this is in other bundle) has three components and they are all "implementation.java" and it is working OK. How can I put a reference to TestService?? Do I need change "implementation.osgi" in CalculatorComponent instead "implementation.java"? and is it neccesary for AddServiceComponent and SubstractService??
I will try a example I will copy my files in the email.
Thank you very much
Un saludo.

Asunto: Re: Fwd: Problem with "implementation.osgi" reference
To access an OSGi service from the SCA component, you will have to provide
SCA configurations for the OSGi bundle so that it becomes an SCA component
using implementation.osgi and the OSGi service becomes an SCA service so
that the Calculator component can wire to that TestService.
There are two SCA files you to provide to model the OSGi bundle as an SCA
component.
* bundle.componentType to describe what OSGi services or references are used
in the bundle (We potentially have better approach to introspect the OSGi
bundle to build this up)
* bundle.composite to configure the component, for example, setting the
bindings.
These files can be in a separate OSGi bundle than the one that owns the
services/references.
Thanks,
Raymond

Subject: Fwd: Problem with "implementation.osgi" reference
Hi
I can not understand this sample because there are many new concepts for me.
For example "bundle.componentType". There is not too much information about
that . I think I need something more simple. I have attached a picture with
my idea.
** When my SCA service was working I had a main component
"implementacion.java" with two references to another two components
(implementation.java). The main component could be invoked as Web Service.
** Now, I want another reference to a Service (TestService in the picture)
that was registered by another different bundle. But this is a OSGi bundle,
without SCA information, Composite file nor ComponentType file. I mean it is
a bundle that is registering a service in the OSGi registry. I need have a
instance wired to this OSGi service in the class of the main Component in
order to invoke their methods.
TestService testService;
//I need testService is not null in order to invoke their methods.
testService.sayHello();
I hope you can understand my problem. You can ask me if you want.
Thank you very mucha

Yes, you are right. I was doing some different tests and I copied you a
wrong composite. I wanted to see if the change of @target made an error in
tuscany. But Tuscany doesn4t recognize this error because I think it
supposes that will be a "remote Component". I can see this in the tuscany
trace
ADVERTENCIA: Component reference target not found, it might be a remote
service running elsewhere in the SCA Domain: Composite =
{http://eclipse.org/SensorNetworkManagement/src/main/resources/SensorNetworkManagement}SensorNetworkManagement
Service = PruebaComponent
But it is Ok, because the component I want if an Osgi Service registered in
the Osgi registry.
I have fixed the error in @target and it is not working yet.
Do you know any example when an <implementation.osgi> component is used?
I have tried to change "xmlns" tag, but it doesn4t work.
<sca:component name="PruebaComponent">

</sca:component>
Thank you very much.

The @target is pointing to a wrong componentName/serviceName. It should be
"Prueba" instead of "PruebaComponent" as the component name is "Prueba".

Subject: Problem with "implementation.osgi" reference
Hello
I want to use an osgi service as a SCA component. But I can not access to
their methods from other Component. I mean I have created a wired instance
to the Osgi Service ($Proxy25). It is not "null" but I can not invoke to one
method because an error is happening
--->Unable to create SCA binding invoker for local target
SensorNetworkManagementComponent reference prueba (bindingURI=null
operation=sayHello)
This is my composite file. I want to have to two components. The first had a
reference to the second and it is normal "implementation.java". The second
is the SCA component that is representing to the Osgi Service that I want to
recover. This Osgi Service was registered in the Osgi registry by Activator
class in "RegistroService" bundle.
<sca:component name="SensorNetworkManagementComponent">
<sca:implementation.java
class="es.amivital.sensornetworkmanagement.sca.SensorNetworkManagementServiceImpl"/>
<sca:service name="SensorNetworkManagementService">
<sca:binding.ws
uri="http://localhost:8085/SensorNetworkManagementComponent"/>
</sca:service>
<sca:reference name="prueba" target="PruebaComponent"/>
</sca:component>
<sca:component name="Prueba">
<sca:implementation.osgi
xmlns="http://tuscany.apache.org/xmlns/sca/1.0"
bundleSymbolicName="RegistroService"
bundleVersion="1.0.0">
<sca:properties service="prueba.PruebaImpl">
</sca:properties>
</sca:implementation.osgi>
</sca:component>
***The Java code--> The first component.
public class SensorNetworkManagementServiceImpl implements
SensorNetworkManagementService {
private Prueba prueba;
public Prueba getPrueba() {
return prueba;
}
@Reference
public void setPrueba(Prueba prueba) {
this.prueba = prueba;
}
}
**Java code --> The second component. It is another bundle that is
registering one simple Osgi Service. The interface was
public interface Prueba {
public abstract String sayHello();
}
This instance (prueba) is not null when an outside client invoke to the
first component. But if I invoke to one method of this interface, for
example "prueba.sayHello" I obtained the previous error.
I have read something about anottations like @AllowsPassByReference or
@Scope, but I don4t know if they are neccesary .
Re: Fwd: Problem with "implementation.osgi" reference

Ok.
I have checked and I don´t need to write code in order to register SCA
node.
Tuscany is trying to register the node with both options
* With "SCA-Composite: true" in the manifest.mf
* Without SCA-Composite header but with a OSGI-INF/sca directory.
The second option has a problem using Eclipse. I have seen the source code
of NodeManager.java and "isSCABundle"
method. bundle.findEntries("OSGI-INF/sca", "*", false) is not working
correctly in Eclipse because tries to find these files in /OSGI-INF/sca but
they are really in /src/main/resources/OSGI-INF/sca. When I pack the bundle
into a jar I have the right structure. But it is not important. I have
copied this structure into the root of my Eclipse project.
I have a new error with both options. Tuscany recognizes the bundle as SCA
bundle but

You don't have to write the code to start the Node. The node-impl-osgi
bundle is watching the SCA enabled OSGi bundles and it will start the Node
when the bundle is started.

Asunto: Re: Fwd: Problem with "implementation.osgi" reference
To access an OSGi service from the SCA component, you will have to provide
SCA configurations for the OSGi bundle so that it becomes an SCA component
using implementation.osgi and the OSGi service becomes an SCA service so
that the Calculator component can wire to that TestService.
There are two SCA files you to provide to model the OSGi bundle as an SCA
component.
* bundle.componentType to describe what OSGi services or references are used
in the bundle (We potentially have better approach to introspect the OSGi
bundle to build this up)
* bundle.composite to configure the component, for example, setting the
bindings.
These files can be in a separate OSGi bundle than the one that owns the
services/references.

Yes, you are right. I was doing some different tests and I copied you a
wrong composite. I wanted to see if the change of @target made an error in
tuscany. But Tuscany doesn4t recognize this error because I think it
supposes that will be a "remote Component". I can see this in the tuscany
trace
ADVERTENCIA: Component reference target not found, it might be a remote
service running elsewhere in the SCA Domain: Composite =
{http://eclipse.org/SensorNetworkManagement/src/main/resources/SensorNetworkManagement}SensorNetworkManagement
Service = PruebaComponent
But it is Ok, because the component I want if an Osgi Service registered in
the Osgi registry.
I have fixed the error in @target and it is not working yet.
Do you know any example when an <implementation.osgi> component is used?
I have tried to change "xmlns" tag, but it doesn4t work.
<sca:component name="PruebaComponent">
<sca:implementation.osgi
xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200903"
bundleSymbolicName="RegistroService"
bundleVersion="1.0.0">
<sca:properties service="prueba.PruebaImpl">
</sca:properties>
</sca:implementation.osgi>
</sca:component>
Thank you very much.

The @target is pointing to a wrong componentName/serviceName. It should be
"Prueba" instead of "PruebaComponent" as the component name is "Prueba".

Subject: Problem with "implementation.osgi" reference
Hello
I want to use an osgi service as a SCA component. But I can not access to
their methods from other Component. I mean I have created a wired instance
to the Osgi Service ($Proxy25). It is not "null" but I can not invoke to one
method because an error is happening
--->Unable to create SCA binding invoker for local target
SensorNetworkManagementComponent reference prueba (bindingURI=null
operation=sayHello)
This is my composite file. I want to have to two components. The first had a
reference to the second and it is normal "implementation.java". The second
is the SCA component that is representing to the Osgi Service that I want to
recover. This Osgi Service was registered in the Osgi registry by Activator
class in "RegistroService" bundle.
<sca:component name="SensorNetworkManagementComponent">
<sca:implementation.java
class="es.amivital.sensornetworkmanagement.sca.SensorNetworkManagementServiceImpl"/>
<sca:service name="SensorNetworkManagementService">
<sca:binding.ws
uri="http://localhost:8085/SensorNetworkManagementComponent"/>
</sca:service>
<sca:reference name="prueba" target="PruebaComponent"/>
</sca:component>
<sca:component name="Prueba">
<sca:implementation.osgi
xmlns="http://tuscany.apache.org/xmlns/sca/1.0"
bundleSymbolicName="RegistroService"
bundleVersion="1.0.0">
<sca:properties service="prueba.PruebaImpl">
</sca:properties>
</sca:implementation.osgi>
</sca:component>
***The Java code--> The first component.
public class SensorNetworkManagementServiceImpl implements
SensorNetworkManagementService {
private Prueba prueba;
public Prueba getPrueba() {
return prueba;
}
@Reference
public void setPrueba(Prueba prueba) {
this.prueba = prueba;
}
}
**Java code --> The second component. It is another bundle that is
registering one simple Osgi Service. The interface was
public interface Prueba {
public abstract String sayHello();
}
This instance (prueba) is not null when an outside client invoke to the
first component. But if I invoke to one method of this interface, for
example "prueba.sayHello" I obtained the previous error.
I have read something about anottations like @AllowsPassByReference or
@Scope, but I don4t know if they are neccesary .

You shouldn't add Service-Component header unless you decide to use OSGi
Declarative Service for your OSGi programming.

Sorry I forgot one question.
I am using this code in order to register CalculatorService as SCA service.
* ** try {*
* ** *
* ** //Registrado el servicio SensorNetworkManagement en el dominio SCA*
* ** NodeFactory factory = NodeFactory.newInstance();*
* ** String url =
ContributionLocationHelper.getContributionLocation(getClass());*
* ** Contribution contrib = new Contribution("c1", url);*
* ** node = factory.createNode("OSGI-INF/sca/bundle.composite",
contrib);*
* ** node.start();*
* ** } catch (Throwable e) {*
* ** e.printStackTrace();*
* ** }*
*
*
Is it neccesary this??? Can I put composite and component type in
"OSGI-INF/sca" directory only? I mean have I to write this code? Does
Tuscany read these files automatically?
Does TestService need this code too?
Thank you very much.

Hello
It seems it is working now. I have launched Tuscany bundles outside and I have installed TestService and Calculator bundle. I am using M3RC1 now. I have to do more tests but when I invoke "add" method" using a external web client, Calculator receives the request and it is able to invoke "sayHello" method from Osgi service that was published by TestService.
But I can not use Eclipse in order to launch Tuscany and doing the same example. I know what the error is. As I commented you Eclipse was having problems in order to detect SCA files located in scr/main/java/resources/sca. I had to copy these files to the project´s root. I think I have a similar error now. It is about contribution.

and I have a new error. I guess tuscany doesn4t like "implementation.osgi" componenents. When I used 2.02M I had another different error.

Besides, I think I will not be able to wire one SCA component osgi with other SCA component java so I want to try other thing. I know tuscany is using its own ClassLoader in order to load classes it needs. But my original problem was I can not share a instance of a Singleton Class between one object loaded by default osgi ClassLoader and other object loaded tuscany ClassLoader.
<rfeng>If your SCA contribution is packaged as OSGi bundles, the classes will be loaded by OSGi. You just need to have the correct Import-Package/Export-Package.</rfeng>
1) I create an instance of one Class that is not modeled with Tuscany
2) I have other Class that will be a Singleton. Only there will be one instance of this class
3) I recover the instance of Singleton class from the instance of step 1
4) A CalculatorImpl instance is created when someone invoke a method from WS (this is a class modeled with Tuscany)
5) CalculatorImpl should recover the same instance of Singleton class
But CalculatorImpl and class of step 1 were loaded by different classLoaders so they will load the Singleton Class twice. So They will have different instances of Singleton class although it was a singleton.

I am checking your comments. I can not remove bundle.composite file from TestService bundle because tuscany is not working without this file.
I have this
Caused by: java.lang.NullPointerException

at org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl$NodeImpl.<init>(NodeFactoryImpl.java:574)
and the source code about this line is
if (composite == null) {
composite = getDefaultComposite(configuration, workspace);
}
// Find the composite in the given contributions
boolean found = false;
Artifact compositeFile = contributionFactory.createArtifact();
compositeFile.setUnresolved(true);
compositeFile.setURI(composite.getURI());
for (Contribution contribution : workspace.getContributions()) {
ModelResolver resolver = contribution.getModelResolver();
// for (Artifact artifact : contribution.getArtifacts()){
// logger.log(Level.INFO,"artifact - " + artifact.getURI());
// }
Artifact resolvedArtifact = resolver.resolveModel(Artifact.class, compositeFile);
// if (!resolvedArtifact.isUnresolved() && resolvedArtifact.getModel() instanceof Composite) {
if (!composite.isUnresolved()) { ---> This is line 440
// The composite content was passed into the node and read into a composite model,
// don't use the composite found in the contribution, use that composite, but just resolve
// it within the context of the contribution
compositeProcessor.resolve(composite, resolver);
} else {
// Use the resolved composite we've found in the contribution
composite = (Composite)resolvedArtifact.getModel();
}
found = true;
// break;
// }
}
I guess composite variable is not null in the first iteration. But it is null when composite = (Composite)resolvedArtifact.getModel(); is executed. So I guess is another problem related with "contribution" because there is a comment about that "// Use the resolved composite we've found in the contribution"
Besides, while I fix these things I am going to use java code in order to register the SCA node. I have checked all your comments about bundle.composite and bundle.componentType at TestService and Calculator bundle. When I invoke to a method of CalculatorService with a WS client I have another problem.
This code of CalculatorServiceImpl
public class CalculatorServiceImpl implements CalculatorService {
private AddService addService;
private TestService testService;
public int add(int param1, int param2) {
System.out.println (testService.sayHello()); --> I have an error when this line is executed
return addService.add(param1, param2);
}
public AddService getAddService() {
return addService;
}
@Reference
public void setAddService(AddService addService) {
this.addService = addService;
}
public TestService getTestService() {
return testService;
}
@Reference
public void setTestService(TestService testService) {
this.testService = testService;
}
}
This is the error . The testService instance is not null but it is not wired to TestService. I have registered the Osgi Service registry using this code in the Activator of TestService bundle. I think this is neccesary.
arg0.registerService(TestService.class.getName(), new TestServiceImpl(), null);

It is necessary to have a bundle.composite file in TestService?? and bundle.componentType?? Can I remove these files from TestService bundle and put the TestService4s bundle.componentType in the Calculator bundle. You said "Alternatively, you have place the file as OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator bundle." Do you mean I can copy TestService4s bundle.componentType into a CalculatorService bundle?
<rfeng>Yes</rfeng>
Thank you very much
-------------------------------------------------------------------
Tuscany checks the OSGi bundle based on one of the following patterns:
* An "SCA-Composite" header in the MANIFEST.MF. It points to an SCA composite file within the bundle.
* Any files under OSGI-INF/sca.
In your case, the first bundle contains three java components. The second bundle contains one OSGi component. There are a few options to get them work together (CalculatorService with a reference to TestService).
Option 1:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The composite contains 4 components: 3 java components and 1 OSGi component.
The @target for CalculatorService component's testService reference will be TestService/<serviceName>.
2) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
Alternatively, you have place the file as OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator bundle.
In this case, we are going to start one Node.
Option 2:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The composite contains 3 java components
2) Place bundle.composite under OSGI-INF/sca in the test service bundle. The composite contains 1 OSGi component.
3) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
In this case, we are going to start two nodes. You can configure the CalculatorService.testService reference and the OSGi service to use the same binding (such as RMI, or WS) to communicate. Make sure the interface is remotable. binding.sca is not working yet.

So, I have to attach two files (componentType and composite) to my two different bundles (TestService and Calculator) and model it as "implementation.osgi". I have TestService in a bundle I will add these two file and I will design as "implementation.osgi" .
But Calculator Service (this is in other bundle) has three components and they are all "implementation.java" and it is working OK. How can I put a reference to TestService?? Do I need change "implementation.osgi" in CalculatorComponent instead "implementation.java"? and is it neccesary for AddServiceComponent and SubstractService??

Asunto: Re: Fwd: Problem with "implementation.osgi" reference
To access an OSGi service from the SCA component, you will have to provide
SCA configurations for the OSGi bundle so that it becomes an SCA component
using implementation.osgi and the OSGi service becomes an SCA service so
that the Calculator component can wire to that TestService.
There are two SCA files you to provide to model the OSGi bundle as an SCA
component.
* bundle.componentType to describe what OSGi services or references are used
in the bundle (We potentially have better approach to introspect the OSGi
bundle to build this up)
* bundle.composite to configure the component, for example, setting the
bindings.
These files can be in a separate OSGi bundle than the one that owns the
services/references.

Subject: Fwd: Problem with "implementation.osgi" reference
Hi
I can not understand this sample because there are many new concepts for me.
For example "bundle.componentType". There is not too much information about
that . I think I need something more simple. I have attached a picture with
my idea.
** When my SCA service was working I had a main component
"implementacion.java" with two references to another two components
(implementation.java). The main component could be invoked as Web Service.
** Now, I want another reference to a Service (TestService in the picture)
that was registered by another different bundle. But this is a OSGi bundle,
without SCA information, Composite file nor ComponentType file. I mean it is
a bundle that is registering a service in the OSGi registry. I need have a
instance wired to this OSGi service in the class of the main Component in
order to invoke their methods.
TestService testService;
//I need testService is not null in order to invoke their methods.
testService.sayHello();
I hope you can understand my problem. You can ask me if you want.
Thank you very mucha

Yes, you are right. I was doing some different tests and I copied you a
wrong composite. I wanted to see if the change of @target made an error in
tuscany. But Tuscany doesn4t recognize this error because I think it
supposes that will be a "remote Component". I can see this in the tuscany
trace
ADVERTENCIA: Component reference target not found, it might be a remote
service running elsewhere in the SCA Domain: Composite =
{http://eclipse.org/SensorNetworkManagement/src/main/resources/SensorNetworkManagement}SensorNetworkManagement
Service = PruebaComponent
But it is Ok, because the component I want if an Osgi Service registered in
the Osgi registry.
I have fixed the error in @target and it is not working yet.
Do you know any example when an <implementation.osgi> component is used?
I have tried to change "xmlns" tag, but it doesn4t work.

Hello
I want to use an osgi service as a SCA component. But I can not access to

method because an error is happening
--->Unable to create SCA binding invoker for local target

This is my composite file. I want to have to two components. The first had a
reference to the second and it is normal "implementation.java". The second
is the SCA component that is representing to the Osgi Service that I want to
recover. This Osgi Service was registered in the Osgi registry by Activator
class in "RegistroService" bundle.

}
This instance (prueba) is not null when an outside client invoke to the
first component. But if I invoke to one method of this interface, for
example "prueba.sayHello" I obtained the previous error.
I have read something about anottations like @AllowsPassByReference or
@Scope, but I don4t know if they are neccesary .
Re: Fwd: Problem with "implementation.osgi" reference
Posted by Raymond Feng <en...@gmail.com>.
I can reproduce the problem now. It's related to how we scan an OSGi bundle. The invalid entries are added from nesting jars. I'm adding code to check if the nested jar is on the bundle classpath to decide if we recursively scan it. I'll check in a fix soon.

It seems it is working now. I have launched Tuscany bundles outside and I have installed TestService and Calculator bundle. I am using M3RC1 now. I have to do more tests but when I invoke "add" method" using a external web client, Calculator receives the request and it is able to invoke "sayHello" method from Osgi service that was published by TestService.
But I can not use Eclipse in order to launch Tuscany and doing the same example. I know what the error is. As I commented you Eclipse was having problems in order to detect SCA files located in scr/main/java/resources/sca. I had to copy these files to the project´s root. I think I have a similar error now. It is about contribution.

<rfeng>You have the wrong namespace for implementation.osgi. It should be xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.1" and tuscany:implementation.osgi.</rfeng>
and I have a new error. I guess tuscany doesn4t like "implementation.osgi" componenents. When I used 2.02M I had another different error.

Besides, I think I will not be able to wire one SCA component osgi with other SCA component java so I want to try other thing. I know tuscany is using its own ClassLoader in order to load classes it needs. But my original problem was I can not share a instance of a Singleton Class between one object loaded by default osgi ClassLoader and other object loaded tuscany ClassLoader.
<rfeng>If your SCA contribution is packaged as OSGi bundles, the classes will be loaded by OSGi. You just need to have the correct Import-Package/Export-Package.</rfeng>
1) I create an instance of one Class that is not modeled with Tuscany
2) I have other Class that will be a Singleton. Only there will be one instance of this class
3) I recover the instance of Singleton class from the instance of step 1
4) A CalculatorImpl instance is created when someone invoke a method from WS (this is a class modeled with Tuscany)
5) CalculatorImpl should recover the same instance of Singleton class
But CalculatorImpl and class of step 1 were loaded by different classLoaders so they will load the Singleton Class twice. So They will have different instances of Singleton class although it was a singleton.

I am checking your comments. I can not remove bundle.composite file from TestService bundle because tuscany is not working without this file.
I have this
Caused by: java.lang.NullPointerException

at org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl$NodeImpl.<init>(NodeFactoryImpl.java:574)
and the source code about this line is
if (composite == null) {
composite = getDefaultComposite(configuration, workspace);
}
// Find the composite in the given contributions
boolean found = false;
Artifact compositeFile = contributionFactory.createArtifact();
compositeFile.setUnresolved(true);
compositeFile.setURI(composite.getURI());
for (Contribution contribution : workspace.getContributions()) {
ModelResolver resolver = contribution.getModelResolver();
// for (Artifact artifact : contribution.getArtifacts()){
// logger.log(Level.INFO,"artifact - " + artifact.getURI());
// }
Artifact resolvedArtifact = resolver.resolveModel(Artifact.class, compositeFile);
// if (!resolvedArtifact.isUnresolved() && resolvedArtifact.getModel() instanceof Composite) {
if (!composite.isUnresolved()) { ---> This is line 440
// The composite content was passed into the node and read into a composite model,
// don't use the composite found in the contribution, use that composite, but just resolve
// it within the context of the contribution
compositeProcessor.resolve(composite, resolver);
} else {
// Use the resolved composite we've found in the contribution
composite = (Composite)resolvedArtifact.getModel();
}
found = true;
// break;
// }
}
I guess composite variable is not null in the first iteration. But it is null when composite = (Composite)resolvedArtifact.getModel(); is executed. So I guess is another problem related with "contribution" because there is a comment about that "// Use the resolved composite we've found in the contribution"
Besides, while I fix these things I am going to use java code in order to register the SCA node. I have checked all your comments about bundle.composite and bundle.componentType at TestService and Calculator bundle. When I invoke to a method of CalculatorService with a WS client I have another problem.
This code of CalculatorServiceImpl
public class CalculatorServiceImpl implements CalculatorService {
private AddService addService;
private TestService testService;
public int add(int param1, int param2) {
System.out.println (testService.sayHello()); --> I have an error when this line is executed
return addService.add(param1, param2);
}
public AddService getAddService() {
return addService;
}
@Reference
public void setAddService(AddService addService) {
this.addService = addService;
}
public TestService getTestService() {
return testService;
}
@Reference
public void setTestService(TestService testService) {
this.testService = testService;
}
}
This is the error . The testService instance is not null but it is not wired to TestService. I have registered the Osgi Service registry using this code in the Activator of TestService bundle. I think this is neccesary.
arg0.registerService(TestService.class.getName(), new TestServiceImpl(), null);

It is necessary to have a bundle.composite file in TestService?? and bundle.componentType?? Can I remove these files from TestService bundle and put the TestService4s bundle.componentType in the Calculator bundle. You said "Alternatively, you have place the file as OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator bundle." Do you mean I can copy TestService4s bundle.componentType into a CalculatorService bundle?
<rfeng>Yes</rfeng>
Thank you very much
-------------------------------------------------------------------
Tuscany checks the OSGi bundle based on one of the following patterns:
* An "SCA-Composite" header in the MANIFEST.MF. It points to an SCA composite file within the bundle.
* Any files under OSGI-INF/sca.
In your case, the first bundle contains three java components. The second bundle contains one OSGi component. There are a few options to get them work together (CalculatorService with a reference to TestService).
Option 1:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The composite contains 4 components: 3 java components and 1 OSGi component.
The @target for CalculatorService component's testService reference will be TestService/<serviceName>.
2) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
Alternatively, you have place the file as OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator bundle.
In this case, we are going to start one Node.
Option 2:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The composite contains 3 java components
2) Place bundle.composite under OSGI-INF/sca in the test service bundle. The composite contains 1 OSGi component.
3) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
In this case, we are going to start two nodes. You can configure the CalculatorService.testService reference and the OSGi service to use the same binding (such as RMI, or WS) to communicate. Make sure the interface is remotable. binding.sca is not working yet.

Subject: Re: Fwd: Problem with "implementation.osgi" reference
So, I have to attach two files (componentType and composite) to my two different bundles (TestService and Calculator) and model it as "implementation.osgi". I have TestService in a bundle I will add these two file and I will design as "implementation.osgi" .
But Calculator Service (this is in other bundle) has three components and they are all "implementation.java" and it is working OK. How can I put a reference to TestService?? Do I need change "implementation.osgi" in CalculatorComponent instead "implementation.java"? and is it neccesary for AddServiceComponent and SubstractService??
I will try a example I will copy my files in the email.

Asunto: Re: Fwd: Problem with "implementation.osgi" reference
To access an OSGi service from the SCA component, you will have to provide
SCA configurations for the OSGi bundle so that it becomes an SCA component
using implementation.osgi and the OSGi service becomes an SCA service so
that the Calculator component can wire to that TestService.
There are two SCA files you to provide to model the OSGi bundle as an SCA
component.
* bundle.componentType to describe what OSGi services or references are used
in the bundle (We potentially have better approach to introspect the OSGi
bundle to build this up)
* bundle.composite to configure the component, for example, setting the
bindings.
These files can be in a separate OSGi bundle than the one that owns the
services/references.

Raymond

Subject: Fwd: Problem with "implementation.osgi" reference
Hi
I can not understand this sample because there are many new concepts for me.
For example "bundle.componentType". There is not too much information about
that . I think I need something more simple. I have attached a picture with
my idea.
** When my SCA service was working I had a main component
"implementacion.java" with two references to another two components
(implementation.java). The main component could be invoked as Web Service.
** Now, I want another reference to a Service (TestService in the picture)
that was registered by another different bundle. But this is a OSGi bundle,
without SCA information, Composite file nor ComponentType file. I mean it is
a bundle that is registering a service in the OSGi registry. I need have a
instance wired to this OSGi service in the class of the main Component in
order to invoke their methods.
TestService testService;
//I need testService is not null in order to invoke their methods.
testService.sayHello();
I hope you can understand my problem. You can ask me if you want.
Thank you very mucha

Yes, you are right. I was doing some different tests and I copied you a
wrong composite. I wanted to see if the change of @target made an error in
tuscany. But Tuscany doesn4t recognize this error because I think it
supposes that will be a "remote Component". I can see this in the tuscany
trace
ADVERTENCIA: Component reference target not found, it might be a remote
service running elsewhere in the SCA Domain: Composite =
{http://eclipse.org/SensorNetworkManagement/src/main/resources/SensorNetworkManagement}SensorNetworkManagement
Service = PruebaComponent
But it is Ok, because the component I want if an Osgi Service registered in
the Osgi registry.
I have fixed the error in @target and it is not working yet.
Do you know any example when an <implementation.osgi> component is used?
I have tried to change "xmlns" tag, but it doesn4t work.

The @target is pointing to a wrong componentName/serviceName. It should be
"Prueba" instead of "PruebaComponent" as the component name is "Prueba".

Hello
I want to use an osgi service as a SCA component. But I can not access to

method because an error is happening
--->Unable to create SCA binding invoker for local target

This is my composite file. I want to have to two components. The first had a
reference to the second and it is normal "implementation.java". The second
is the SCA component that is representing to the Osgi Service that I want to
recover. This Osgi Service was registered in the Osgi registry by Activator
class in "RegistroService" bundle.

This instance (prueba) is not null when an outside client invoke to the

Hello
It seems it is working now. I have launched Tuscany bundles outside and I
have installed TestService and Calculator bundle. I am using M3RC1 now. I
have to do more tests but when I invoke "add" method" using a external web
client, Calculator receives the request and it is able to invoke "sayHello"
method from Osgi service that was published by TestService.
But I can not use Eclipse in order to launch Tuscany and doing the same
example. I know what the error is. As I commented you Eclipse was having
problems in order to detect SCA files located in
scr/main/java/resources/sca. I had to copy these files to the project´s
root. I think I have a similar error now. It is about contribution.

Hi,
Please see my comments inline.
BTW, can you send your testcase? I can point you what to fix.

Hello.
I have downloaded M3RC1 but I have the same errors. I can not run this in
Eclipse but I think it is my problem. I run this distribution outside of
Eclipse and all modules are running. But when I try to run my TestService
bundle I have an error
GRAVE: org.oasisopen.sca.ServiceRuntimeException: Deployment composite
OSGI-INF/
sca/bundle.composite cannot be found within contribution bundleentry://181/
java.lang.IllegalStateException: org.oasisopen.sca.ServiceRuntimeException:
Depl
oyment composite OSGI-INF/sca/bundle.composite cannot be found within
contributi
on bundleentry://181/
<rfeng>The isSCABundle() checking is too relaxed. We should check the
existence of OSGI-INF/sca/bundle.composite or SCA-Composite header instead
of any files under OSGI-INF/sca. I'm checking in a fix soon.</rfeng>
I think composite.file is always compulsory. It is not enough with
bunde.componentType as you said. Well, I put one composite file in order to
test it
<rfeng>Please don't add the composite file if you already have the OSGi
component defined in the calculator.composite</rfeng>
<sca:composite xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.1"

<sca:component name="TestServiceComponent">
<sca:implementation.osgi bundleSymbolicName="TestService"

</sca:component>
</sca:composite>
<rfeng>You have the wrong namespace for implementation.osgi. It should be
xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.1" and
tuscany:implementation.osgi.</rfeng>
and I have a new error. I guess tuscany doesn´t like "implementation.osgi"
componenents. When I used 2.02M I had another different error.

Besides, I think I will not be able to wire one SCA component osgi with

problem was I can not share a instance of a Singleton Class between one
object loaded by default osgi ClassLoader and other object loaded tuscany
ClassLoader.
<rfeng>If your SCA contribution is packaged as OSGi bundles, the classes
will be loaded by OSGi. You just need to have the correct
Import-Package/Export-Package.</rfeng>
1) I create an instance of one Class that is not modeled with Tuscany
2) I have other Class that will be a Singleton. Only there will be one
instance of this class
3) I recover the instance of Singleton class from the instance of step 1
4) A CalculatorImpl instance is created when someone invoke a method from WS
(this is a class modeled with Tuscany)
5) CalculatorImpl should recover the same instance of Singleton class
But CalculatorImpl and class of step 1 were loaded by different classLoaders
so they will load the Singleton Class twice. So They will have different
instances of Singleton class although it was a singleton.

I am checking your comments. I can not remove bundle.composite file from
TestService bundle because tuscany is not working without this file.
I have this
Caused by: java.lang.NullPointerException
at
org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl.configureNode(NodeFactoryImpl.java:440)

at
org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl$NodeImpl.<init>(NodeFactoryImpl.java:574)
and the source code about this line is
if (composite == null) {
composite = getDefaultComposite(configuration, workspace);
}
// Find the composite in the given contributions
boolean found = false;
Artifact compositeFile = contributionFactory.createArtifact();
compositeFile.setUnresolved(true);
compositeFile.setURI(composite.getURI());
for (Contribution contribution : workspace.getContributions()) {
ModelResolver resolver = contribution.getModelResolver();
// for (Artifact artifact :
contribution.getArtifacts()){
// logger.log(Level.INFO,"artifact - " +
artifact.getURI());
// }
Artifact resolvedArtifact =
resolver.resolveModel(Artifact.class, compositeFile);
// if (!resolvedArtifact.isUnresolved() &&
resolvedArtifact.getModel() instanceof Composite) {
if (!composite.isUnresolved()) { ---> This is line 440
// The composite content was passed into the node and read
into a composite model,
// don't use the composite found in the contribution, use
that composite, but just resolve
// it within the context of the contribution
compositeProcessor.resolve(composite, resolver);
} else {
// Use the resolved composite we've found in the
contribution
composite = (Composite)resolvedArtifact.getModel();
}
found = true;
// break;
// }
}
I guess composite variable is not null in the first iteration. But it is
null when composite = (Composite)resolvedArtifact.getModel(); is executed.
So I guess is another problem related with "contribution" because there is a
comment about that "// Use the resolved composite we've found in the
contribution"
Besides, while I fix these things I am going to use java code in order to
register the SCA node. I have checked all your comments about
bundle.composite and bundle.componentType at TestService and Calculator
bundle. When I invoke to a method of CalculatorService with a WS client I
have another problem.
This code of CalculatorServiceImpl
public class CalculatorServiceImpl implements CalculatorService {
private AddService addService;
private TestService testService;
public int add(int param1, int param2) {
System.out.println (testService.sayHello()); --> I have an error when this
line is executed
return addService.add(param1, param2);
}
public AddService getAddService() {
return addService;
}
@Reference
public void setAddService(AddService addService) {
this.addService = addService;
}
public TestService getTestService() {
return testService;
}
@Reference
public void setTestService(TestService testService) {
this.testService = testService;
}
}
This is the error . The testService instance is not null but it is not wired
to TestService. I have registered the Osgi Service registry using this code
in the Activator of TestService bundle. I think this is neccesary.
arg0.registerService(TestService.class.getName(), new TestServiceImpl(),

It is necessary to have a bundle.composite file in TestService?? and
bundle.componentType?? Can I remove these files from TestService bundle and
put the TestService4s bundle.componentType in the Calculator bundle. You
said "Alternatively, you have place the file as
OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator
bundle." Do you mean I can copy TestService4s bundle.componentType into a
CalculatorService bundle?
<rfeng>Yes</rfeng>
Thank you very much
-------------------------------------------------------------------
Tuscany checks the OSGi bundle based on one of the following patterns:
* An "SCA-Composite" header in the MANIFEST.MF. It points to an SCA
composite file within the bundle.
* Any files under OSGI-INF/sca.
In your case, the first bundle contains three java components. The second
bundle contains one OSGi component. There are a few options to get them
work together (CalculatorService with a reference to TestService).
Option 1:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The
composite contains 4 components: 3 java components and 1 OSGi component.
The @target for CalculatorService component's testService reference will be
TestService/<serviceName>.
2) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
Alternatively, you have place the file as
OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator
bundle.
In this case, we are going to start one Node.
Option 2:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The
composite contains 3 java components
2) Place bundle.composite under OSGI-INF/sca in the test service bundle. The
composite contains 1 OSGi component.
3) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
In this case, we are going to start two nodes. You can configure the
CalculatorService.testService reference and the OSGi service to use the same
binding (such as RMI, or WS) to communicate. Make sure the interface is
remotable. binding.sca is not working yet.

Subject: Re: Fwd: Problem with "implementation.osgi" reference
So, I have to attach two files (componentType and composite) to my two
different bundles (TestService and Calculator) and model it as
"implementation.osgi". I have TestService in a bundle I will add these two

But Calculator Service (this is in other bundle) has three components and
they are all "implementation.java" and it is working OK. How can I put a

Asunto: Re: Fwd: Problem with "implementation.osgi" reference
To access an OSGi service from the SCA component, you will have to provide
SCA configurations for the OSGi bundle so that it becomes an SCA component
using implementation.osgi and the OSGi service becomes an SCA service so
that the Calculator component can wire to that TestService.
There are two SCA files you to provide to model the OSGi bundle as an SCA
component.
* bundle.componentType to describe what OSGi services or references are used
in the bundle (We potentially have better approach to introspect the OSGi
bundle to build this up)
* bundle.composite to configure the component, for example, setting the
bindings.
These files can be in a separate OSGi bundle than the one that owns the
services/references.

Subject: Fwd: Problem with "implementation.osgi" reference
Hi
I can not understand this sample because there are many new concepts for me.
For example "bundle.componentType". There is not too much information about
that . I think I need something more simple. I have attached a picture with
my idea.
** When my SCA service was working I had a main component
"implementacion.java" with two references to another two components
(implementation.java). The main component could be invoked as Web Service.
** Now, I want another reference to a Service (TestService in the picture)
that was registered by another different bundle. But this is a OSGi bundle,
without SCA information, Composite file nor ComponentType file. I mean it is
a bundle that is registering a service in the OSGi registry. I need have a
instance wired to this OSGi service in the class of the main Component in
order to invoke their methods.
TestService testService;
//I need testService is not null in order to invoke their methods.
testService.sayHello();
I hope you can understand my problem. You can ask me if you want.
Thank you very mucha

Subject: Re: Problem with "implementation.osgi" reference
Yes, you are right. I was doing some different tests and I copied you a
wrong composite. I wanted to see if the change of @target made an error in
tuscany. But Tuscany doesn4t recognize this error because I think it
supposes that will be a "remote Component". I can see this in the tuscany
trace
ADVERTENCIA: Component reference target not found, it might be a remote
service running elsewhere in the SCA Domain: Composite =
{http://eclipse.org/SensorNetworkManagement/src/main/resources/SensorNetworkManagement}SensorNetworkManagement
Service = PruebaComponent
But it is Ok, because the component I want if an Osgi Service registered in
the Osgi registry.
I have fixed the error in @target and it is not working yet.
Do you know any example when an <implementation.osgi> component is used?
I have tried to change "xmlns" tag, but it doesn4t work.

The @target is pointing to a wrong componentName/serviceName. It should be
"Prueba" instead of "PruebaComponent" as the component name is "Prueba".

Hello
I want to use an osgi service as a SCA component. But I can not access to

method because an error is happening
--->Unable to create SCA binding invoker for local target

This is my composite file. I want to have to two components. The first had a
reference to the second and it is normal "implementation.java". The second
is the SCA component that is representing to the Osgi Service that I want to
recover. This Osgi Service was registered in the Osgi registry by Activator
class in "RegistroService" bundle.

}
This instance (prueba) is not null when an outside client invoke to the
first component. But if I invoke to one method of this interface, for
example "prueba.sayHello" I obtained the previous error.
I have read something about anottations like @AllowsPassByReference or

Re: Fwd: Problem with "implementation.osgi" reference
Posted by Raymond Feng <en...@gmail.com>.
Which level of the Tuscany 2.x code are you using? The various issues you ran into seem to have been fixed before. Can you try our M3 RC1?

Subject: Re: Fwd: Problem with "implementation.osgi" reference
I am checking your comments. I can not remove bundle.composite file from TestService bundle because tuscany is not working without this file.
I have this
Caused by: java.lang.NullPointerException
at org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl.configureNode(NodeFactoryImpl.java:440)
at org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl.access$2(NodeFactoryImpl.java:351)
at org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl$NodeImpl.<init>(NodeFactoryImpl.java:574)
and the source code about this line is
if (composite == null) {
composite = getDefaultComposite(configuration, workspace);
}
// Find the composite in the given contributions
boolean found = false;
Artifact compositeFile = contributionFactory.createArtifact();
compositeFile.setUnresolved(true);
compositeFile.setURI(composite.getURI());
for (Contribution contribution : workspace.getContributions()) {
ModelResolver resolver = contribution.getModelResolver();
// for (Artifact artifact : contribution.getArtifacts()){
// logger.log(Level.INFO,"artifact - " + artifact.getURI());
// }
Artifact resolvedArtifact = resolver.resolveModel(Artifact.class, compositeFile);
// if (!resolvedArtifact.isUnresolved() && resolvedArtifact.getModel() instanceof Composite) {
if (!composite.isUnresolved()) { ---> This is line 440
// The composite content was passed into the node and read into a composite model,
// don't use the composite found in the contribution, use that composite, but just resolve
// it within the context of the contribution
compositeProcessor.resolve(composite, resolver);
} else {
// Use the resolved composite we've found in the contribution
composite = (Composite)resolvedArtifact.getModel();
}
found = true;
// break;
// }
}
I guess composite variable is not null in the first iteration. But it is null when composite = (Composite)resolvedArtifact.getModel(); is executed. So I guess is another problem related with "contribution" because there is a comment about that "// Use the resolved composite we've found in the contribution"
Besides, while I fix these things I am going to use java code in order to register the SCA node. I have checked all your comments about bundle.composite and bundle.componentType at TestService and Calculator bundle. When I invoke to a method of CalculatorService with a WS client I have another problem.
This code of CalculatorServiceImpl
public class CalculatorServiceImpl implements CalculatorService {
private AddService addService;
private TestService testService;
public int add(int param1, int param2) {
System.out.println (testService.sayHello()); --> I have an error when this line is executed
return addService.add(param1, param2);
}
public AddService getAddService() {
return addService;
}
@Reference
public void setAddService(AddService addService) {
this.addService = addService;
}
public TestService getTestService() {
return testService;
}
@Reference
public void setTestService(TestService testService) {
this.testService = testService;
}
}
This is the error . The testService instance is not null but it is not wired to TestService. I have registered the Osgi Service registry using this code in the Activator of TestService bundle. I think this is neccesary.
arg0.registerService(TestService.class.getName(), new TestServiceImpl(), null);

Tuscany checks the OSGi bundle based on one of the following patterns:
* An "SCA-Composite" header in the MANIFEST.MF. It points to an SCA composite file within the bundle.
* Any files under OSGI-INF/sca.
In your case, the first bundle contains three java components. The second bundle contains one OSGi component. There are a few options to get them work together (CalculatorService with a reference to TestService).
Option 1:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The composite contains 4 components: 3 java components and 1 OSGi component.
The @target for CalculatorService component's testService reference will be TestService/<serviceName>.
2) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
Alternatively, you have place the file as OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator bundle.
In this case, we are going to start one Node.
Option 2:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The composite contains 3 java components
2) Place bundle.composite under OSGI-INF/sca in the test service bundle. The composite contains 1 OSGi component.
3) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
In this case, we are going to start two nodes. You can configure the CalculatorService.testService reference and the OSGi service to use the same binding (such as RMI, or WS) to communicate. Make sure the interface is remotable. binding.sca is not working yet.

Asunto: Re: Fwd: Problem with "implementation.osgi" reference
To access an OSGi service from the SCA component, you will have to provide
SCA configurations for the OSGi bundle so that it becomes an SCA component
using implementation.osgi and the OSGi service becomes an SCA service so
that the Calculator component can wire to that TestService.
There are two SCA files you to provide to model the OSGi bundle as an SCA
component.
* bundle.componentType to describe what OSGi services or references are used
in the bundle (We potentially have better approach to introspect the OSGi
bundle to build this up)
* bundle.composite to configure the component, for example, setting the
bindings.
These files can be in a separate OSGi bundle than the one that owns the
services/references.

Hi
I can not understand this sample because there are many new concepts for me.
For example "bundle.componentType". There is not too much information about
that . I think I need something more simple. I have attached a picture with
my idea.
** When my SCA service was working I had a main component
"implementacion.java" with two references to another two components
(implementation.java). The main component could be invoked as Web Service.
** Now, I want another reference to a Service (TestService in the picture)
that was registered by another different bundle. But this is a OSGi bundle,
without SCA information, Composite file nor ComponentType file. I mean it is
a bundle that is registering a service in the OSGi registry. I need have a
instance wired to this OSGi service in the class of the main Component in
order to invoke their methods.
TestService testService;
//I need testService is not null in order to invoke their methods.
testService.sayHello();
I hope you can understand my problem. You can ask me if you want.
Thank you very mucha

Subject: Re: Problem with "implementation.osgi" reference
Yes, you are right. I was doing some different tests and I copied you a
wrong composite. I wanted to see if the change of @target made an error in
tuscany. But Tuscany doesn4t recognize this error because I think it
supposes that will be a "remote Component". I can see this in the tuscany
trace
ADVERTENCIA: Component reference target not found, it might be a remote
service running elsewhere in the SCA Domain: Composite =
{http://eclipse.org/SensorNetworkManagement/src/main/resources/SensorNetworkManagement}SensorNetworkManagement
Service = PruebaComponent
But it is Ok, because the component I want if an Osgi Service registered in
the Osgi registry.
I have fixed the error in @target and it is not working yet.
Do you know any example when an <implementation.osgi> component is used?
I have tried to change "xmlns" tag, but it doesn4t work.
<sca:component name="PruebaComponent">
<sca:implementation.osgi

</sca:implementation.osgi>
</sca:component>
Thank you very much.

The @target is pointing to a wrong componentName/serviceName. It should be
"Prueba" instead of "PruebaComponent" as the component name is "Prueba".

Subject: Problem with "implementation.osgi" reference
Hello
I want to use an osgi service as a SCA component. But I can not access to
their methods from other Component. I mean I have created a wired instance
to the Osgi Service ($Proxy25). It is not "null" but I can not invoke to one
method because an error is happening
--->Unable to create SCA binding invoker for local target
SensorNetworkManagementComponent reference prueba (bindingURI=null
operation=sayHello)
This is my composite file. I want to have to two components. The first had a
reference to the second and it is normal "implementation.java". The second
is the SCA component that is representing to the Osgi Service that I want to
recover. This Osgi Service was registered in the Osgi registry by Activator
class in "RegistroService" bundle.
<sca:component name="SensorNetworkManagementComponent">
<sca:implementation.java
class="es.amivital.sensornetworkmanagement.sca.SensorNetworkManagementServiceImpl"/>
<sca:service name="SensorNetworkManagementService">
<sca:binding.ws
uri="http://localhost:8085/SensorNetworkManagementComponent"/>
</sca:service>
<sca:reference name="prueba" target="PruebaComponent"/>
</sca:component>
<sca:component name="Prueba">
<sca:implementation.osgi
xmlns="http://tuscany.apache.org/xmlns/sca/1.0"
bundleSymbolicName="RegistroService"
bundleVersion="1.0.0">
<sca:properties service="prueba.PruebaImpl">
</sca:properties>
</sca:implementation.osgi>
</sca:component>
***The Java code--> The first component.
public class SensorNetworkManagementServiceImpl implements
SensorNetworkManagementService {
private Prueba prueba;
public Prueba getPrueba() {
return prueba;
}
@Reference
public void setPrueba(Prueba prueba) {
this.prueba = prueba;
}
}
**Java code --> The second component. It is another bundle that is
registering one simple Osgi Service. The interface was
public interface Prueba {
public abstract String sayHello();
}
This instance (prueba) is not null when an outside client invoke to the
first component. But if I invoke to one method of this interface, for
example "prueba.sayHello" I obtained the previous error.
I have read something about anottations like @AllowsPassByReference or
@Scope, but I don4t know if they are neccesary .
Re: Fwd: Problem with "implementation.osgi" reference
Posted by Santiago Miguel Aranda Rojas <sa...@gmail.com>.
I am checking your comments. I can not remove bundle.composite file from
TestService bundle because tuscany is not working without this file.
I have this
Caused by: java.lang.NullPointerException
*at
org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl.configureNode(NodeFactoryImpl.java:440)
*
at
org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl.access$2(NodeFactoryImpl.java:351)
at
org.apache.tuscany.sca.node.osgi.impl.NodeFactoryImpl$NodeImpl.<init>(NodeFactoryImpl.java:574)
and the source code about this line is
if (composite == null) {
composite = getDefaultComposite(configuration, workspace);
}
// Find the composite in the given contributions
boolean found = false;
Artifact compositeFile = contributionFactory.createArtifact();
compositeFile.setUnresolved(true);
compositeFile.setURI(composite.getURI());
for (Contribution contribution : workspace.getContributions()) {
ModelResolver resolver = contribution.getModelResolver();
// for (Artifact artifact :
contribution.getArtifacts()){
// logger.log(Level.INFO,"artifact - " +
artifact.getURI());
// }
Artifact resolvedArtifact =
resolver.resolveModel(Artifact.class, compositeFile);
// if (!resolvedArtifact.isUnresolved() &&
resolvedArtifact.getModel() instanceof Composite) {
* if (!composite.isUnresolved()) { ---> This is line 440*
// The composite content was passed into the node and read
into a composite model,
// don't use the composite found in the contribution, use
that composite, but just resolve
// it within the context of the contribution
compositeProcessor.resolve(composite, resolver);
} else {
// Use the resolved composite we've found in the
contribution
composite = (Composite)resolvedArtifact.getModel();
}
found = true;
// break;
// }
}
I guess composite variable is not null in the first iteration. But it is
null when* composite = (Composite)resolvedArtifact.getModel();* is executed.
So I guess is another problem related with "contribution" because there is a
comment about that *"// Use the resolved composite we've found in the
contribution"*
*
*
Besides, while I fix these things I am going to use java code in order to
register the SCA node. I have checked all your comments about
bundle.composite and bundle.componentType at TestService and Calculator
bundle. When I invoke to a method of CalculatorService with a WS client I
have another problem.
This code of CalculatorServiceImpl
public class CalculatorServiceImpl implements CalculatorService {
private AddService addService;
private TestService testService;
public int add(int param1, int param2) {
*System.out.println (testService.sayHello()); --> I have an error when this
line is executed*
return addService.add(param1, param2);
}
public AddService getAddService() {
return addService;
}
@Reference
public void setAddService(AddService addService) {
this.addService = addService;
}
public TestService getTestService() {
return testService;
}
@Reference
public void setTestService(TestService testService) {
this.testService = testService;
}
}
This is the error . The testService instance is not null but it is not wired
to TestService. I have registered the Osgi Service registry using this code
in the Activator of TestService bundle. I think this is neccesary.
* **arg0.registerService(TestService.class.getName(), new TestServiceImpl(),
null); *

It is necessary to have a bundle.composite file in TestService?? and
bundle.componentType?? Can I remove these files from TestService bundle and
put the TestService´s bundle.componentType in the Calculator bundle. You
said "Alternatively, you have place the file as
OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator
bundle." Do you mean I can copy TestService´s bundle.componentType into a
CalculatorService bundle?
<rfeng>Yes</rfeng>
Thank you very much
-------------------------------------------------------------------
Tuscany checks the OSGi bundle based on one of the following patterns:
* An "SCA-Composite" header in the MANIFEST.MF. It points to an SCA
composite file within the bundle.
* Any files under OSGI-INF/sca.
In your case, the first bundle contains three java components. The second
bundle contains one OSGi component. There are a few options to get them
work together (CalculatorService with a reference to TestService).
Option 1:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The
composite contains 4 components: 3 java components and 1 OSGi component.
The @target for CalculatorService component's testService reference will be
TestService/<serviceName>.
2) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
Alternatively, you have place the file as
OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator
bundle.
In this case, we are going to start one Node.
Option 2:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The
composite contains 3 java components
2) Place bundle.composite under OSGI-INF/sca in the test service bundle. The
composite contains 1 OSGi component.
3) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
In this case, we are going to start two nodes. You can configure the
CalculatorService.testService reference and the OSGi service to use the same
binding (such as RMI, or WS) to communicate. Make sure the interface is
remotable. binding.sca is not working yet.

Subject: Re: Fwd: Problem with "implementation.osgi" reference
So, I have to attach two files (componentType and composite) to my two
different bundles (TestService and Calculator) and model it as
"implementation.osgi". I have TestService in a bundle I will add these two
file and I will design as "implementation.osgi" .
But Calculator Service (this is in other bundle) has three components and
they are all "implementation.java" and it is working OK. How can I put a
reference to TestService?? Do I need change "implementation.osgi" in
CalculatorComponent instead "implementation.java"? and is it neccesary for
AddServiceComponent and SubstractService??
I will try a example I will copy my files in the email.
Thank you very much

Asunto: Re: Fwd: Problem with "implementation.osgi" reference
To access an OSGi service from the SCA component, you will have to provide
SCA configurations for the OSGi bundle so that it becomes an SCA component
using implementation.osgi and the OSGi service becomes an SCA service so
that the Calculator component can wire to that TestService.
There are two SCA files you to provide to model the OSGi bundle as an SCA
component.
* bundle.componentType to describe what OSGi services or references are used
in the bundle (We potentially have better approach to introspect the OSGi
bundle to build this up)
* bundle.composite to configure the component, for example, setting the
bindings.
These files can be in a separate OSGi bundle than the one that owns the
services/references.

Subject: Fwd: Problem with "implementation.osgi" reference
Hi
I can not understand this sample because there are many new concepts for me.
For example "bundle.componentType". There is not too much information about
that . I think I need something more simple. I have attached a picture with
my idea.
** When my SCA service was working I had a main component
"implementacion.java" with two references to another two components
(implementation.java). The main component could be invoked as Web Service.
** Now, I want another reference to a Service (TestService in the picture)
that was registered by another different bundle. But this is a OSGi bundle,
without SCA information, Composite file nor ComponentType file. I mean it is
a bundle that is registering a service in the OSGi registry. I need have a
instance wired to this OSGi service in the class of the main Component in
order to invoke their methods.
TestService testService;
//I need testService is not null in order to invoke their methods.
testService.sayHello();
I hope you can understand my problem. You can ask me if you want.
Thank you very mucha

Yes, you are right. I was doing some different tests and I copied you a
wrong composite. I wanted to see if the change of @target made an error in
tuscany. But Tuscany doesn4t recognize this error because I think it
supposes that will be a "remote Component". I can see this in the tuscany
trace
ADVERTENCIA: Component reference target not found, it might be a remote
service running elsewhere in the SCA Domain: Composite =
{http://eclipse.org/SensorNetworkManagement/src/main/resources/SensorNetworkManagement}SensorNetworkManagement
Service = PruebaComponent
But it is Ok, because the component I want if an Osgi Service registered in
the Osgi registry.
I have fixed the error in @target and it is not working yet.
Do you know any example when an <implementation.osgi> component is used?
I have tried to change "xmlns" tag, but it doesn4t work.

The @target is pointing to a wrong componentName/serviceName. It should be
"Prueba" instead of "PruebaComponent" as the component name is "Prueba".

Hello
I want to use an osgi service as a SCA component. But I can not access to
their methods from other Component. I mean I have created a wired instance
to the Osgi Service ($Proxy25). It is not "null" but I can not invoke to one
method because an error is happening
--->Unable to create SCA binding invoker for local target
SensorNetworkManagementComponent reference prueba (bindingURI=null
operation=sayHello)
This is my composite file. I want to have to two components. The first had a
reference to the second and it is normal "implementation.java". The second
is the SCA component that is representing to the Osgi Service that I want to
recover. This Osgi Service was registered in the Osgi registry by Activator
class in "RegistroService" bundle.

@Reference
public void setPrueba(Prueba prueba) {
this.prueba = prueba;
}
}
**Java code --> The second component. It is another bundle that is
registering one simple Osgi Service. The interface was
public interface Prueba {
public abstract String sayHello();
}
This instance (prueba) is not null when an outside client invoke to the
first component. But if I invoke to one method of this interface, for
example "prueba.sayHello" I obtained the previous error.
I have read something about anottations like @AllowsPassByReference or
@Scope, but I don4t know if they are neccesary .

Re: Fwd: Problem with "implementation.osgi" reference
Posted by Raymond Feng <en...@gmail.com>.
Tuscany checks the OSGi bundle based on one of the following patterns:
* An "SCA-Composite" header in the MANIFEST.MF. It points to an SCA
composite file within the bundle.
* Any files under OSGI-INF/sca.
In your case, the first bundle contains three java components. The second
bundle contains one OSGi component. There are a few options to get them
work together (CalculatorService with a reference to TestService).
Option 1:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The
composite contains 4 components: 3 java components and 1 OSGi component.
The @target for CalculatorService component's testService reference will be
TestService/<serviceName>.
2) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
Alternatively, you have place the file as
OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator
bundle.
In this case, we are going to start one Node.
Option 2:
1) Place bundle.composite under OSGI-INF/sca in the calculator bundle. The
composite contains 3 java components
2) Place bundle.composite under OSGI-INF/sca in the test service bundle. The
composite contains 1 OSGi component.
3) Place bundle.componentType under OSGI-INF/sca in the test service bundle.
In this case, we are going to start two nodes. You can configure the
CalculatorService.testService reference and the OSGi service to use the same
binding (such as RMI, or WS) to communicate. Make sure the interface is
remotable. binding.sca is not working yet.

Asunto: Re: Fwd: Problem with "implementation.osgi" reference
To access an OSGi service from the SCA component, you will have to provide
SCA configurations for the OSGi bundle so that it becomes an SCA component
using implementation.osgi and the OSGi service becomes an SCA service so
that the Calculator component can wire to that TestService.
There are two SCA files you to provide to model the OSGi bundle as an SCA
component.
* bundle.componentType to describe what OSGi services or references are used
in the bundle (We potentially have better approach to introspect the OSGi
bundle to build this up)
* bundle.composite to configure the component, for example, setting the
bindings.
These files can be in a separate OSGi bundle than the one that owns the
services/references.

Hi
I can not understand this sample because there are many new concepts for me.
For example "bundle.componentType". There is not too much information about

my idea.
** When my SCA service was working I had a main component
"implementacion.java" with two references to another two components

** Now, I want another reference to a Service (TestService in the picture)
that was registered by another different bundle. But this is a OSGi bundle,

Subject: Re: Problem with "implementation.osgi" reference
Yes, you are right. I was doing some different tests and I copied you a
wrong composite. I wanted to see if the change of @target made an error in
tuscany. But Tuscany doesn´t recognize this error because I think it
supposes that will be a "remote Component". I can see this in the tuscany
trace
ADVERTENCIA: Component reference target not found, it might be a remote
service running elsewhere in the SCA Domain: Composite =
{http://eclipse.org/SensorNetworkManagement/src/main/resources/SensorNetworkManagement}SensorNetworkManagement
Service = PruebaComponent
But it is Ok, because the component I want if an Osgi Service registered in
the Osgi registry.
I have fixed the error in @target and it is not working yet.
Do you know any example when an <implementation.osgi> component is used?
I have tried to change "xmlns" tag, but it doesn´t work.
<sca:component name="PruebaComponent">
<sca:implementation.osgi

</sca:component>
Thank you very much.

The @target is pointing to a wrong componentName/serviceName. It should be
"Prueba" instead of "PruebaComponent" as the component name is "Prueba".

Hello
I want to use an osgi service as a SCA component. But I can not access to
their methods from other Component. I mean I have created a wired instance
to the Osgi Service ($Proxy25). It is not "null" but I can not invoke to one
method because an error is happening
--->Unable to create SCA binding invoker for local target
SensorNetworkManagementComponent reference prueba (bindingURI=null
operation=sayHello)
This is my composite file. I want to have to two components. The first had a
reference to the second and it is normal "implementation.java". The second
is the SCA component that is representing to the Osgi Service that I want to
recover. This Osgi Service was registered in the Osgi registry by Activator
class in "RegistroService" bundle.
<sca:component name="SensorNetworkManagementComponent">
<sca:implementation.java
class="es.amivital.sensornetworkmanagement.sca.SensorNetworkManagementServiceImpl"/>
<sca:service name="SensorNetworkManagementService">

SensorNetworkManagementService {

}
@Reference
public void setPrueba(Prueba prueba) {
this.prueba = prueba;
}
}
**Java code --> The second component. It is another bundle that is
registering one simple Osgi Service. The interface was
public interface Prueba {
public abstract String sayHello();
}
This instance (prueba) is not null when an outside client invoke to the
first component. But if I invoke to one method of this interface, for
example "prueba.sayHello" I obtained the previous error.
I have read something about anottations like @AllowsPassByReference or
@Scope, but I don´t know if they are neccesary .
Fwd: Problem with "implementation.osgi" reference
Posted by Santiago Miguel Aranda Rojas <sa...@gmail.com>.
Hi
I can not understand this sample because there are many new concepts for me.
For example "bundle.componentType". There is not too much information about
that . I think I need something more simple. I have attached a picture with
my idea.
** When my SCA service was working I had a main component
"implementacion.java" with two references to another two components
(implementation.java). The main component could be invoked as Web Service.
** Now, I want another reference to a Service (TestService in the picture)
that was registered by another different bundle. But this is a OSGi bundle,
without SCA information, Composite file nor ComponentType file. I mean it is
a bundle that is registering a service in the OSGi registry. I need have a
instance wired to this OSGi service in the class of the main Component in
order to invoke their methods.
TestService testService;
//I need testService is not null in order to invoke their methods.
testService.sayHello();
I hope you can understand my problem. You can ask me if you want.
Thank you very mucha

The second is the SCA component that is representing to the Osgi Service that I want to recover. This Osgi Service was registered in the Osgi registry by Activator class in "RegistroService" bundle.
<sca:component name="SensorNetworkManagementComponent">
<sca:implementation.java class="es.amivital.sensornetworkmanagement.sca.SensorNetworkManagementServiceImpl"/>
<sca:service name="SensorNetworkManagementService">
<sca:binding.ws uri="http://localhost:8085/SensorNetworkManagementComponent"/>
</sca:service>
<sca:reference name="prueba" target="PruebaComponent"/>
</sca:component>
<sca:component name="Prueba">
<sca:implementation.osgi xmlns="http://tuscany.apache.org/xmlns/sca/1.0"
bundleSymbolicName="RegistroService"
bundleVersion="1.0.0">
<sca:properties service="prueba.PruebaImpl">
</sca:properties>
</sca:implementation.osgi>
</sca:component>
***The Java code--> The first component.
public class SensorNetworkManagementServiceImpl implements SensorNetworkManagementService {
private Prueba prueba;
public Prueba getPrueba() {
return prueba;
}
@Reference
public void setPrueba(Prueba prueba) {
this.prueba = prueba;
}
}
**Java code --> The second component. It is another bundle that is registering one simple Osgi Service. The interface was
public interface Prueba {
public abstract String sayHello();
}
This instance (prueba) is not null when an outside client invoke to the first component. But if I invoke to one method of this interface, for example "prueba.sayHello" I obtained the previous error.
I have read something about anottations like @AllowsPassByReference or @Scope, but I don´t know if they are neccesary .
