I have the same problem, trying to find whats wrong. Now I think the problem is with XDoclet.

In Response To: 

I'm trying to figure out why remote access to my EJB works but local access doesn't seem to.  If I create a test remote test client using the following code, everything seems to work fine.


  | 	Hashtable env = new Hashtable();
  | 	env.put(Context.INITIAL_CONTEXT_FACTORY, 
  | 	    "org.jnp.interfaces.NamingContextFactory");
  | 	env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
  | 
  | 	try {
  | 		LeagueFacade leagueFacade = LeagueFacadeUtil.getHome(env).create();
  | 		League league = leagueFacade.findLeague(1);
  | 

If I use the following code in a jsp or servlet deployed as part of the same EAR into the Jboss container, I get an exception (failing on the call to LeagueFacadeUtil.getHome() ).

  | 	LeagueFacadeHome h = LeagueFacadeUtil.getHome();
  | 	LeagueFacade l = h.create();
  | 	League league = l.findLeague(1);
  | 	Iterator schedules = league.getSchedules()
  | 			.iterator();
  |

  | 	com.leagueplanet.ejb.LeagueFacadeUtil.getHome(LeagueFacadeUtil.java:42)
  | 	org.apache.jsp.schedule_jsp._jspService(schedule_jsp.java:78)
  | 

If I try to add an initial context environment as I did for the remote client, I get a different exception and it fails on the call to LeagueFacadeHome.create()

  | 	org.jboss.ejb.SessionContainer.internalInvokeHome(SessionContainer
  | 

I'm obviously missing something but can't quite figure out what it is.  BTW, this is the basic code from the WTP book, which was aimed at a JBoss 4.0 deployment.

Thanks,
