Callback and Tuscany 2.0 Samples
Hi
I am evaluating Tuscany 2.0 Beta1 and am trying to learn more about
Callbacks (Bi-Directional interface) of SCA 1.1.
I downloaded the Tuscany Sample files and started to explore the callback
implementations with webservice binding, i.e. the Search and SearchCallback
interfaces.
It took me a while before I realized that the Tuscany SCA Samples were based
on SCA v1.0. Tuscany 2.0 Beta1 is based on the SCA v1.1 specs.
After studying the sample sources, I have written my own callback.
Unfortunately, I kept on getting a runtime exception after I installed and
deployed my contribution. By the way, I am using Eclipse and the maven
tuscany plugin.
I can't find the problem and hope if someone can point me in the right
direction.
This is the error (printed on my console) I am getting when I try to run my
program:
[ERROR] Failed to execute goal
org.apache.tuscany.maven.plugins:maven-tuscany-plugin:2.0-Beta1:run
(default-cli) on project handler-agent: Execution default-cli of goal
org.apache.tuscany.maven.plugins:maven-tuscany-plugin:2.0-Beta1:run failed:

MessageInterpreterComponent] - [ASM60033] No targets for reference:
Composite = {http://docs.oasis-open.org/ns/opencsa/sca/200912} Reference =
messageInterpreterCallback -> [Help 1]
I suspect that I am doing something wrong in the composite file. I can't
imagine I did something wrong in the java sources. (See below for the
sources.)
Kind Regards,
Urso

Hi Urso,
I've tried just about every possible combination of dependencies in the
build/plugin element and I get errors every time. What combination are
you using?

Please do.
It saves a lot of pain and time trying to make it work. (Well, it won't
really work).

Fwd: Callback and Tuscany 2.0 Samples
Posted by ant elder <an...@apache.org>.
We've not done anything about this yet so unless anyone says otherwise
i'm going to move the jaxws versions of the WS binding out to contrib.
I still think it would be good to have the version that works with
just Java and no other dependencies but until we have that working
more completely or someone working on it then it seems better to not
be confusing users like this.

Hi Ant,
Well, I suggest to remove JAXWS RI. Some SCA characteristics such as
Callback through binding.ws are not working properly.
I use the maven tuscany plugin in Eclipse to build my projects. (Ease
of use and development)

Re: Callback and Tuscany 2.0 Samples
Posted by ant elder <an...@gmail.com>.
Might you have multiple versions of the Tuscany artifacts being used?
I don't have 2.0-Beta1 artifacts so just used 2.0-SNAPSHOT to try it,
but if your pom.xml now has dependencies using both versions that
might be confusing things.

I tried this (using mvn tuscany:run from the command line) and I get
the stack trace shown below.
I assume that the messages about duplicate bindings and intents can
be ignored. I'm not sure if I should be concerned about the
PrivilegedActionException. The NoSuchMethodError is a showstopper.
Any ideas what could cause this?

Re: Callback and Tuscany 2.0 Samples
Posted by ant elder <an...@gmail.com>.
You should be able to use the Axis2 based WS binding with the Tuscany
plugin instead of the JAXWS RI based one by adding the dependencies as
follows:
<plugin>
<groupId>org.apache.tuscany.maven.plugins</groupId>
<artifactId>maven-tuscany-plugin</artifactId>
<version>2.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.apache.tuscany.sca</groupId>
<artifactId>tuscany-binding-ws-runtime-axis2</artifactId>
<version>2.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty</artifactId>
<version>6.1.19</version>
</dependency>
</dependencies>
</plugin>
We need to decide if we want to keep maintaining the JAXWS RI based WS
binding or drop it and just use the Axis2 based one, its not getting
updated much these days so is getting out of date, i guess thats a
discussion for the dev list.
It would be interesting to hear a bit more about how you use the
Tuscany plugin, you say you use it in Eclipse, could you tell us a bit
more about what you do?

Hi Urso,
I tried this pom but I get an error when running the maven Junit test

Re: Callback and Tuscany 2.0 Samples
Posted by Urso Wieske <uw...@gmail.com>.
Simon,
Checkout my POM.
I had also to remove two dependencies you suggested me to add originally.
I kept my base-runtime dependency by the way.

Re: Callback and Tuscany 2.0 Samples
Posted by Urso Wieske <uw...@gmail.com>.
Simon,
I added the dependencies AS PART OF the maven plugin dependency element.
(Dependencies element enclosed in the build/plugins/plugin element).
Then it should work!
Kind regards,
Urso

Re: Callback and Tuscany 2.0 Samples
Posted by Urso Wieske <uw...@gmail.com>.
Hi Simon,
I have been studying the source code around SCA binding.ws extension.
As you mentioned earlier, the Tuscany SCA runtime uses by default de
reference implementation of JAX-WS binding.
In the resource of binding-ws-runtime-jaxws-ri at the path
META-INF/services/org.apache.tuscany.sca.provider.BindingProviderFactory:
org.apache.tuscany.sca.binding.ws.jaxws.ri.JAXWSBindingProviderFactory;model=org.apache.tuscany.sca.binding.ws.WebServiceBinding
you can indeed see that the Factory JAXWSBindingProviderFactory is used as
default.
I believe -I have not digged into the code yet- that the reference
implementation is overridden as soon as the SCA runtime finds an alternative
binding.ws implementation on the classpath.
I check this by just adding the Axis2 extension to my dependency set and I
the runtime appears switch automatically to Axis2.
I manage to run my code with the maven plugin. I removed
<dependency>
<groupId>org.apache.tuscany.sca</groupId>
<artifactId>tuscany-node-impl</artifactId>
<version>2.0-Beta1</version>
</dependency>
<dependency>
<groupId>org.apache.tuscany.sca</groupId>
<artifactId>tuscany-implementation-java-runtime</artifactId>
<version>2.0-Beta1</version>
</dependency>
from my dependencyset and ran my code succesfully.
I don't understand the "negative" effect of these two dependencies on my
code.
Maybe you have some clarification for this?
Kind Regards,
Urso

Re: Callback and Tuscany 2.0 Samples
Posted by Urso Wieske <uw...@gmail.com>.
Hi Simon,
Could you send me a copy of your POM which you have used /adapted?
Also which public repositories are you using to download your Tuscany 2.0
Beta1 dependencies?
(I have initially googled for a oublic maven repository where I could
donwload the Tuscany v2 Beta1 dependencies.)
I replaced my base runtime for the 4 dependencies you have stated, but I get
runtime exceptions due to other causes. Most probably I should have other
dependencies too which you have not mentioned.
Kind regards.
Urso

Re: Callback and Tuscany 2.0 Samples
Posted by Urso Wieske <uw...@gmail.com>.
Hi Simon,
Thanks for the quick response.
That's a pitty that maven-tuscany-plugin is not behaving accordingly. It's a
great instrument to use within my IDE (Eclipse). I'll submit an issue at the
Tuscany projectsite. I will also dig into the "maven-tuscany-plugin" problem
to figure out what is the cause of this deviation.
Kind Regards
Urso

Re: Callback and Tuscany 2.0 Samples

Hi Urso,
This problem is caused by a bug in Tuscany. Please raise a JIRA
so that we can track and fix the problem. In the meantime, I can
suggest a partial workaround.
The injection failure only happens if Tuscany is using the
tuscany-binding-ws-runtime-jaxws module as the runtime implementation
for <binding.ws>. It doesn't happen if tuscany-binding-ws-runtime-axis2
is used instead of tuscany-binding-ws-runtime-jaxws. This implies that
the problem is caused by a bug in the -jaxws version.
By default, Tuscany uses the -jaxws version. To get Tuscany to use
the -axis2 version instead, you need to do special configuration in
the pom.xml file.
Unfortunately I couldn't find a way to make this change when using
maven-tuscany-plugin to run the application. This is because
maven-tuscany-plugin has a dependency on tuscany-base-runtime.
The tuscany-base-runtime jar contains the -jaxws version and seems
to always use it even if the -axis2 version is declared as an
additional dependency.
I did find a way to get Tuscany to use the -axis2 version when not
using maven-tuscany-plugin. If you replace this dependency:
<dependency>
<groupId>org.apache.tuscany.sca</groupId>
<artifactId>tuscany-base-runtime</artifactId>
<version>2.0-Beta1</version>
</dependency>
by the following four dependencies:
<dependency>
<groupId>org.apache.tuscany.sca</groupId>
<artifactId>tuscany-binding-ws-runtime-axis2</artifactId>
<version>2.0-Beta1</version>
</dependency>
<dependency>
<groupId>org.apache.tuscany.sca</groupId>
<artifactId>tuscany-host-jetty</artifactId>
<version>2.0-Beta1</version>
</dependency>
<dependency>
<groupId>org.apache.tuscany.sca</groupId>
<artifactId>tuscany-node-impl</artifactId>
<version>2.0-Beta1</version>
</dependency>
<dependency>
<groupId>org.apache.tuscany.sca</groupId>
<artifactId>tuscany-implementation-java-runtime</artifactId>
<version>2.0-Beta1</version>
</dependency>
then the application runs successfully. I used a maven JUnit test
to verify this.

Re: Callback and Tuscany 2.0 Samples
Posted by Urso Wieske <uw...@gmail.com>.
Hi Simon,
I have uploaded my sources as a zipped file.
Hi Simon,
I adapted my code as you suggested. It seems like the error has
dissappeared, but I got new ones.
Well I removed the setter and getter of messageInterpreterCallback from
MessageInterpreterImpl. Now my MessageInterpreterImpl class contains only
the instance variable messageInterpreterCallback . I have made it a
protected variable.
I get a HTTP Internal Server ( error 500).
I am still missing something.SCA runtime is supposed "automatically" inject
my callback instance in the messageInterpreterCallback member variable of
MessageInterpreterImpl. The MessageInterpreterImpl needs to have a reference
to some callback instance.
I can;t seem to solve this problem.
This is the error....

According to the SCA 1.1 specs, this variable should be private
in order to avoid having it treated as a reference. Can you try
changing this and see if it makes any difference?

From the stack trace it seems that the thread message context doesn't
contain the callback endpoint. I'm not sure what could cause this.
However I noticed a problem in your composite that would be worth
fixing, and it's just possible that this might be related to the
problem that you're seeing.
The problem is that you have specified a callback URI for the
MessageInterpreter service in MessageInterpreterComponent, as follows:
<service name="MessageInterpreter">
<interface.java interface="org.acme.logix.MessageInterpreter"
callbackInterface="org.acme.logix.MessageInterpreterCallback"/>
<binding.ws uri="http://localhost:8081/MessageInterpreterComponent/MessageInterpreter"/>
<callback>
<binding.ws uri="http://localhost:8084/Client/MessageInterpreterCallback"/>
</callback>
</service>
There shouldn't be any callback URI in the service definition, because
this information is provided at runtime by the client invocation. So
you should change the above to:
<service name="MessageInterpreter">
<interface.java interface="org.acme.logix.MessageInterpreter"
callbackInterface="org.acme.logix.MessageInterpreterCallback"/>
<binding.ws uri="http://localhost:8081/MessageInterpreterComponent/MessageInterpreter"/>
<callback>
<binding.ws/>
</callback>
</service>
If neither of these suggested changes fixes the problem, please
post the complete application as a zip file.

Re: Callback and Tuscany 2.0 Samples
Posted by Urso Wieske <uw...@gmail.com>.
Hi Simon,
I adapted my code as you suggested. It seems like the error has
dissappeared, but I got new ones.
Well I removed the setter and getter of messageInterpreterCallback from
MessageInterpreterImpl. Now my MessageInterpreterImpl class contains only
the instance variable messageInterpreterCallback . I have made it a
protected variable.
I get a HTTP Internal Server ( error 500).
I am still missing something.SCA runtime is supposed "automatically" inject
my callback instance in the messageInterpreterCallback member variable of
MessageInterpreterImpl. The MessageInterpreterImpl needs to have a reference
to some callback instance.
I can;t seem to solve this problem.
This is the error....

Because the MessageInterpreterImpl class doesn't contain any @Reference or
@Property annotations, SCA creates implicit references for all public
setter methods in this class whose type is a remotable SCA interface, and
also for all public or protected fields in this class whose type is a
remotable SCA interface.
There is a public setter method setMessageInterpreterCallback() and a
protected field messageInterpreterCallback, so SCA defines a reference
named messageInterpreterCallback. This reference doesn't have a target
configured in the composite, hence the error message.
To fix the problem, you need to remove the setter method (or make it
protected) and change the field from protected to private.
