The lookup code is:

    private ISession getRemoteSession() throws Throwable {
        final Properties env = new Properties();
        env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.cosnaming.CNCtxFactory");
        env.put(Context.PROVIDER_URL,
"corbaloc::localhost:7001/NameService");

        final InitialContext context = new InitialContext(env);
        final Object iiopObj = context.lookup("SessionBean");
        return
ISessionHome.class.cast(javax.rmi.PortableRemoteObject.narrow(iiopObj,
ISessionHome.class)).create();
    }

and the stacktrace is:
