[jboss-user] [EJB/JBoss] - ClassNotFoundException talking to remote EJB

[pixel]

Hi

I am trying to access a remote stateless session bean, which returns an interface. The interface is IStringWrapper which is an interface to StringWrapper, which has a single method, getString().

The bean looks like this:
	
  | public void ejbCreate() throws CreateException {
  | }
  | 
  | public IStringWrapper getStringWrapper() {
  | 	Log.debug( this, "Returning new StringWrapper with \"hello\"" );
  | 	return new StringWrapper( "hello" );
  | }
  | 

when I include the StringWrapper class in my client, everything works as expected, and I get the String "hello". If I leave out the StringWrapper class, and just include the IStringWrapper interface in the client, I get the following exception:

  | Exception in thread "main" java.lang.reflect.UndeclaredThrowableException
  |         at $Proxy1.getStringWrapper(Unknown Source)
  |         at ejb.client.TestClient.getStringWrapper(TestClient.java:43)
  |         at Test.main(Test.java:25)
  | Caused by: java.lang.ClassNotFoundException: ejb.results.containers.StringWrapper
  |         at java.net.URLClassLoader$1.run(URLClassLoader.java:199)
  | 

initially I got a reference to "(no security manager: RMI class loader disabled)" which I fixed with a security policy, but I still get the ClassNotFoundException.

Am I being a complete noob here, and misunderstanding the process. I thought that the ejb could return an interface, so that the client doesn't need the actual class. Is this not the case, or have I messed up something else fundamental. I know I am hitting the server, as the debug messages are showing up.

Thanks
