            RemoteException, RemoveException, CreateException {
  Properties p=System.getProperties();
  p.put(Context.INITIAL_CONTEXT_FACTORY,
 "weblogic.jndi.WLInitialContextFactory");
  p.put(Context.PROVIDER_URL, "t3://localhost:7001/hello");

   Context ctx=new InitialContext(p);
    Object obj=ctx.lookup("Hello");
    HelloHome home=(HelloHome)PortableRemoteObject.narrow(obj,HelloHome.class);
