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?

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); Caused by: org.oasisopen.sca.ServiceUnavailableException: Unable to create SCA binding invoker for local target CalculatorComponent reference testService (bindingURI=null operation=sayHello) at org.apache.tuscany.sca.binding.sca.provider.RuntimeSCAReferenceBindingProvider.createInvoker(RuntimeSCAReferenceBindingProvider.java:200) --------------------------------------------- 2009/6/17 Raymond Feng <[email protected]> Hi, Please see my comments inline.

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.

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.

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.

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.

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. 2009/6/10 Raymond Feng <[email protected]> The @target is pointing to a wrong componentName/serviceName.

I have read something about anottations like @AllowsPassByReference or @Scope, but I don4t know if they are neccesary .
