Hello all, I'm having some trouble with java user defined exception that does not propagate correctly through RMI binding. The test is working well when no exception is raised behind a RMI binding. (I've simplified it to match a simpler case but not removing key element for example: long package name replaced by a short one).
I have a component (n°1) using another component (n°2), which is also using another component (n°3). All connexions are done with RMI bindings. It might happen that one component is down due to various troubles. Let say my last component is down. The third component will fail to contact it and raise: org.apache.tuscany.sca.host.rmi.RMIHostRuntimeException: Connection refused to host: localhost; nested exception is: java.net.ConnectException: Connection refused: connect That is normal, in my second component I will catch it without problem and I'm going to throw it with my user defined exception : test.UserDefinedException (an user defined public class which extends an user defined public abstract class (test.UserAbstractException that extends Exception and Implements Serializable)). Now in my first component, I'm catching this exception (I'm trying to catch UserDefinedException but instead I'm getting an other exception that was not handled): It might be a problem caused by the use of user defined exception that is not fully defined for tuscany java.lang.reflect.UndeclaredThrowableException at $Proxy10.test2(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.tuscany.sca.binding.rmi.RMIReferenceInvoker.invokeTarget(RMIReferenceInvoker.java:74) at org.apache.tuscany.sca.binding.rmi.RMIReferenceInvoker.invoke(RMIReferenceInvoker.java:51) at org.apache.tuscany.sca.extension.helper.impl.InvokerProxy.invoke(BindingsActivator.java:252) at org.apache.tuscany.sca.core.databinding.wire.PassByValueInterceptor.invoke(PassByValueInterceptor.java:108) at org.apache.tuscany.sca.core.invocation.JDKInvocationHandler.invoke(JDKInvocationHandler.java:286) at org.apache.tuscany.sca.core.invocation.JDKInvocationHandler.invoke(JDKInvocationHandler.java:154) at $Proxy6.test2(Unknown Source) at compo1.test2a(Compo1.java:93) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.tuscany.sca.implementation.java.invocation.JavaImplementationInvoker.invoke(JavaImplementationInvoker.java:109) at org.apache.tuscany.sca.binding.sca.impl.SCABindingInvoker.invoke(SCABindingInvoker.java:61) at org.apache.tuscany.sca.core.invocation.JDKInvocationHandler.invoke(JDKInvocationHandler.java:286) at org.apache.tuscany.sca.core.invocation.JDKInvocationHandler.invoke(JDKInvocationHandler.java:154) at $Proxy5.test2a(Unknown Source) at webapp.TestAction.execute(TestAction.java:98) at org.apache.struts.chain.commands.servlet.ExecuteAction.execute(ExecuteAction.java:58) at org.apache.struts.chain.commands.AbstractExecuteAction.execute(AbstractExecuteAction.java:67) at org.apache.struts.chain.commands.ActionCommandBase.execute(ActionCommandBase.java:51) at org.apache.commons.chain.impl.ChainBase.execute(ChainBase.java:190) at org.apache.commons.chain.generic.LookupCommand.execute(LookupCommand.java:304) at org.apache.commons.chain.impl.ChainBase.execute(ChainBase.java:190) at org.apache.struts.chain.ComposableRequestProcessor.process(ComposableRequestProcessor.java:283) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1913) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:462) at javax.servlet.http.HttpServlet.service(HttpServlet.java:710) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.tuscany.sca.host.webapp.TuscanyServletFilter.doFilter(TuscanyServletFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:433) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:595) Caused by: java.rmi.UnexpectedException: unexpected exception;
