    Local ejb access vs remote access

    Mark Secrist Newbie

      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();
      


      java.lang.ClassCastException

       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()
      root cause
      
      java.rmi.ServerException: EJBException:; nested exception is:

       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,
