EJB3 access issue between portal 2.7.2 and AS 5.1.0GA
I've deployed an EJB3 service on JBoss AS 5.1.0.GA. I now want to interact with this service from portlets deployed on JBoss Portal 2.7.2 (on JBoss AS 4.2.3). For some reason the remoting fails with a NullPointerException.
Caused by: java.lang.NullPointerException at org.jboss.ejb3.stateless.StatelessContainer.dynamicInvoke(StatelessContainer.java:379) at org.jboss.ejb3.session.InvokableContextClassProxyHack._dynamicInvoke(InvokableContextClassProxyHack.java:53) at org.jboss.aop.Dispatcher.invoke(Dispatcher.java:91) at org.jboss.aspects.remoting.AOPRemotingInvocationHandler.invoke(AOPRemotingInvocationHandler.java:82) at org.jboss.remoting.ServerInvoker.invoke(ServerInvoker.java:891) at org.jboss.remoting.transport.socket.ServerThread.completeInvocation(ServerThread.java:744) at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:697) at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:524) at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:232) at org.jboss.remoting.MicroRemoteClientInvoker.invoke(MicroRemoteClientInvoker.java:163) at org.jboss.remoting.Client.invoke(Client.java:1634) at org.jboss.remoting.Client.invoke(Client.java:548) at org.jboss.aspects.remoting.InvokeRemoteInterceptor.invoke(InvokeRemoteInterceptor.java:62) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.tx.ClientTxPropagationInterceptor.invoke(ClientTxPropagationInterceptor.java:67) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.security.client.SecurityClientInterceptor.invoke(SecurityClientInterceptor.java:65) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.remoting.IsLocalInterceptor.invoke(IsLocalInterceptor.java:74) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.aspects.remoting.PojiProxy.invoke(PojiProxy.java:61) at $Proxy295.invoke(Unknown Source) at org.jboss.ejb3.proxy.impl.handler.session.SessionProxyInvocationHandlerBase.invoke(SessionProxyInvocationHandlerBase.java:207) at org.jboss.ejb3.proxy.impl.handler.session.SessionProxyInvocationHandlerBase.invoke(SessionProxyInvocationHandlerBase.java:164)
Is this a bug or is there an incompatibility between version 4.2.3 and 5.1.0.GA? Should I instead be running both servers on level 4.2.3? Maybe this is a classloading issue, since I can access the service from a CLI environment without a problem.
Thank you
