tuscany 2 and SCADomain

I am using tuscany 2.0-M4 to run ram's sample from here

http://svn.apache.org/repos/asf/tuscany/sandbox/ramkumar/helloworld-ws-reference/

I can't find the SCADomain class, is it deprecated? what should I use now?
Is there an equivalent sample for tuscany 2?

*

public* *class* HelloWorldClient {

*public* *final* *static* *void* main(String[] args) *throws* Exception {

SCADomain scaDomain = SCADomain.newInstance("helloworldwsclient.composite");

HelloWorldService helloWorldService =
scaDomain.getService(HelloWorldService.*class*, "HelloWorldServiceComponent"
);

OMFactory fac = OMAbstractFactory.*getOMFactory*();

OMElement imageElement = fac.createOMElement("image", *null*);

// Creating the Data Handler for the file.

DataHandler dataHandler = *new* DataHandler(*new* FileDataSource(
"C:/attachedfile.jpg"));

//create an OMText node with the above DataHandler and set optimized to true

OMText textData = fac.createOMText(dataHandler, *true*);

imageElement.addChild(textData);

String value = helloWorldService.getGreetings("attachedfile.jpg",
imageElement);

System.*out*.println(value);

scaDomain.close();

}

}

i found this
http://cwiki.apache.org/TUSCANYxDOCx2x/converting-tuscany-1x-extensions.html

Changed client code to


String contribution = ContributionLocationHelper.*getContributionLocation*
(HelloWorldService.*class*);

Node node = NodeFactory.*newInstance*().createNode(
"helloworldwsclient.composite",

*new* Contribution("test", contribution));

node.start();

HelloWorldService helloWorldService = node.getService(HelloWorldService.*
class*, "HelloTuscanyServiceComponent");

And Now I got hit by the bug
http://issues.apache.org/jira/browse/TUSCANY-2664

Is there a workaround?

Thanks

Similar as the service side:

Node  node = NodeFactory.newInstance().createNode(""helloworldwsclient.composite", this.getClass().getClassLoader()).start();
HelloWorldService helloWorldService  = node.getService(HelloWorldService.class, "HelloWorldServiceComponent"); 
...

Thanks!

So I was able to start the service

Now what do I change the client code to?

SCADomain scaDomain = SCADomain.newInstance(

"helloworldwsclient.composite"); 
HelloWorldService helloWorldService = scaDomain.getService(HelloWorldService.

class, "HelloWorldServiceComponent"); 

OMFactory fac = OMAbstractFactory.getOMFactory();

OMElement imageElement = fac.createOMElement(

"image", null); 

// Creating the Data Handler for the file. 
DataHandler dataHandler = 

new DataHandler(new FileDataSource("C:/attachedfile.jpg")); 

//create an OMText node with the above DataHandler and set optimized to true 
OMText textData = fac.createOMText(dataHandler, 

true); 
imageElement.addChild(textData); 

String value = helloWorldService.getGreetings(

"attachedfile.jpg", imageElement); 
System.

out.println(value); 

scaDomain.close();

Or even better just use call createNode with the explicit contribution
location, for example:

        Node node = NodeFactory.newInstance().createNode(null, new
String[] {"target/classes"}).start();

I'd like to get that API simplified even further but have't got to it
yet, so you should be able to just do:

       Node node =
NodeFactory.newInstance().createNode("target/classes").start();

   ...ant

Re: tuscany 2 and SCADomain

Please use NodeFactory/Node APIs instead. For example,

        String location = ContributionLocationHelper.getContributionLocation(SampleClient.class);
        Node node = NodeFactory.newInstance().createNode(new Contribution("c1", location));
        
        node.start();

        SampleClient sampleClient = node.getService(SampleClient.class, "SampleClient");
        sampleClient.runSample();

Thanks,
Raymond
