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.

The node-impl-osgi bundle is watching the SCA enabled OSGi bundles and it will start the Node when the bundle is started. Thanks, Raymond From: Santiago Miguel Aranda Rojas Sent: Tuesday, June 16, 2009 1:44 AM To: [email protected] Subject: Re: Fwd: Problem with "implementation.osgi" reference 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. 2009/6/16 <[email protected]> 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.

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 From: Santiago Miguel Aranda Rojas Sent: Monday, June 15, 2009 4:01 AM To: [email protected] 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.

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. It should be "Prueba" instead of "PruebaComponent" as the component name is "Prueba".

From: [email protected] Sent: Tuesday, June 09, 2009 9:15 AM To: [email protected] 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 .
