[jboss-user] [EJB/JBoss] - Remote client calls problem after migration to JBoss AS 5

Hello everyone, i try to migrate my JBoss 4.2.2 Application (and an Eclipse based remote client) to JBoss 5.0.0. I am getting some exceptions during remote calls of SLSBs and SFSBs on my client. The context creation and lookup has been performed correctly. As I see in the server log, the SFSB has been created. Calling method sendTextMessage of a SLSB causes: java.lang.NullPointerException | at org.jboss.ejb3.stateless.StatelessContainer.dynamicInvoke(StatelessContainer.java:444) | at org.jboss.ejb3.session.InvokableContextClassProxyHack._dynamicInvoke(InvokableContextClassProxyHack.java:56) | at org.jboss.aop.Dispatcher.invoke(Dispatcher.java:91) | ... | at org.jboss.aspects.remoting.PojiProxy.invoke(PojiProxy.java:61) | at $Proxy3.invoke(Unknown Source) | at org.jboss.ejb3.proxy.handler.ProxyInvocationHandlerBase.invoke(ProxyInvocationHandlerBase.java:261) | at org.jboss.ejb3.proxy.handler.session.SessionSpecProxyInvocationHandlerBase.invoke(SessionSpecProxyInvocationHandlerBase.java:101) | at $Proxy2.sendTextMessage(Unknown Source) | at client.Client.main(Client.java:31) Calling method retrieve of SFSB causes: java.lang.ClassCastException: org.jboss.aop.joinpoint.MethodInvocation cannot be cast to org.jboss.ejb3.stateful.StatefulRemoteInvocation | at org.jboss.ejb3.stateful.StatefulContainer.dynamicInvoke(StatefulContainer.java:552) | at org.jboss.ejb3.session.InvokableContextClassProxyHack._dynamicInvoke(InvokableContextClassProxyHack.java:56) | at org.jboss.aop.Dispatcher.invoke(Dispatcher.java:91) | ... | at org.jboss.aspects.remoting.PojiProxy.invoke(PojiProxy.java:61) | at $Proxy3.invoke(Unknown Source) | at org.jboss.ejb3.proxy.handler.ProxyInvocationHandlerBase.invoke(ProxyInvocationHandlerBase.java:261) | at org.jboss.ejb3.proxy.handler.session.SessionSpecProxyInvocationHandlerBase.invoke(SessionSpecProxyInvocationHandlerBase.java:101) | at $Proxy2.retrieve(Unknown Source) | at client.Client.main(Client.java:36) Could that be a Class-Path problem? jbossall-client.jar and all it's dependencies are available... Client and server are running on JDK 1.5.0. Any ideas? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4231444#...
