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 $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 $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?
