Hi, These last few days I've been looking into calculator2, as suggested by Luciano. I took a list of necessary modules that Adriano sent me from the calculator2 jars and augmented it until the point in which I received the same error stack trace [1] that he reported in this thread. I am now getting the same errors on the Android Emulator [2] and have posted the error stack trace in [3]. An excerpt of this trace is included below and a couple of questions follow it afterwards.
ERROR/AndroidRuntime(2255): Caused by: org.osoa.sca.ServiceUnavailableException: Service not found for component CalculatorServiceComponent reference setAddService (bindingURI=null operation=add). Ensure that the composite containing the service is loaded and started somewhere in the SCA domain and that if running in a remote node that the interface of the target service marked as @Remotable ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.binding.sca.impl.RuntimeSCAReferenceBindingProvider.createInvoker(RuntimeSCAReferenceBindingProvider.java:247) ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.core.assembly.RuntimeWireImpl.addReferenceBindingInterceptor(RuntimeWireImpl.java:228) ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.core.assembly.RuntimeWireImpl.initInvocationChains(RuntimeWireImpl.java:167) ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.core.assembly.RuntimeWireImpl.getInvocationChains(RuntimeWireImpl.java:109) ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.core.invocation.JDKInvocationHandler.getInvocationChain(JDKInvocationHandler.java:243) ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.core.invocation.JDKInvocationHandler.invoke(JDKInvocationHandler.java:148) ERROR/AndroidRuntime(2255): at $Proxy2.add(Native Method) ERROR/AndroidRuntime(2255): at calculator.CalculatorServiceImpl.add(CalculatorServiceImpl.java:55) ERROR/AndroidRuntime(2255): at java.lang.reflect.Method.invokeNative(Native Method) ERROR/AndroidRuntime(2255): at java.lang.reflect.Method.invoke(Method.java:356) ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.implementation.java.invocation.JavaImplementationInvoker.invoke(JavaImplementationInvoker.java:109) ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.binding.sca.impl.SCABindingInvoker.invoke(SCABindingInvoker.java:61) ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.core.invocation.JDKInvocationHandler.invoke(JDKInvocationHandler.java:286) ERROR/AndroidRuntime(2255): at org.apache.tuscany.sca.core.invocation.JDKInvocationHandler.invoke(JDKInvocationHandler.java:154) ERROR/AndroidRuntime(2255): at $Proxy1.add(Native Method) How can I ensure that the composite containing the service is being loaded? The full stack trace includes warnings for CompositeBuilderImpl not having the appropriate component references. This makes me think that the composite is not being created and thus results in the errors above. Am I missing something? Suggestions are welcomed and appreciated. The resulting set of modules is based on the tuscany-runtime2 and tuscany-api jars from revision 673092. In the context of this thread [4] in which grouping and aggregating modules was discussed I am now a user looking to embed Tuscany functionality in Android. The thread helped me to identify the subset of Tuscany to port, it consists of the modules shown below: android-jdk-classes tuscany-assembly tuscany-assembly-xml tuscany-binding-sca tuscany-binding-sca-xml tuscany-contribution tuscany-contribution-impl tuscany-contribution-java tuscany-contribution-namespace tuscany-contribution-resource tuscany-contribution-xml tuscany-core tuscany-core-databinding tuscany-core-spi tuscany-databinding tuscany-databinding-jaxb tuscany-definitions tuscany-definitions-xml tuscany-domain tuscany-domain-api tuscany-extensibility tuscany-host-embedded tuscany-host-http tuscany-host-webapp tuscany-host-webapp-junit tuscany-implementation-java tuscany-implementation-java-runtime tuscany-implementation-java-xml tuscany-interface tuscany-interface-java tuscany-interface-java-jaxws tuscany-interface-java-xml tuscany-node tuscany-node-api tuscany-policy tuscany-policy-logging tuscany-policy-xml tuscany-sca-api [1] http://cwiki.apache.org/confluence/display/TUSCANYWIKI/SCA+Android+Exception+after+revision+674723 [2] http://androidindelft.googlepages.com/21Jul2.jpg [3] http://cwiki.apache.org/confluence/display/TUSCANYWIKI/21Jul2008-2+-+Error+Stack+trace [4] http://www.mail-archive.com/[email protected]/msg00390.html On Tue, Jul 8, 2008 at 8:33 AM, Adriano Crestani <[EMAIL PROTECTED]> wrote: > Thanks Luciano, good suggestion...I will check this sample later ; ) > > For now, I have commited some modifications I have done on the android > sandbox: > > - the code that uses the Java RMI API was commented > > - the code that uses the JWS API was also commented > > - the code that uses the Introspector.decapitalize() (Java Beans API) > method was replaced by the logic this method provides > > - It was also throwing a NPE when SCA tries to load the > TransformationExtensionPoint, so I loaded the > DefaultTransformationExtensionPoint programatically > > After this modifications, I had to add the core-databinding, interface-java > and inteface-java-jws modules to the android sandbox. > > I think we are almost there to get the SCA first-run on the Android > platform...for now we are getting this exception: [1] > > Adriano Crestani > > [1] - > http://cwiki.apache.org/confluence/display/TUSCANYWIKI/SCA+Android+Exception+after+revision+674723 > > > > On Mon, Jul 7, 2008 at 3:58 PM, Luciano Resende <[EMAIL PROTECTED]> > wrote: > >> Just my 2c, Did you guys see what Ant did with calculator2 ?
