Hello World EJB problems

Question

Hi,
I'm currently reading Mastering EJB, 2nd edition and I'm trying to get my first ejb to work.
I managed to deploy it and i've wrote the client, but it simply won't run :-(
Here is my code:
public class HelloClient
     public static void main(String[] args) throws NamingException, RemoteException, CreateException
          Hashtable env = new Hashtable(11);
          env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
          env.put(Context.PROVIDER_URL,"ldap://127.0.0.1:1050");
          env.put(Context.SECURITY_AUTHENTICATION,"none");
          Context ctx = new InitialContext(env);
          Object obj = ctx.lookup("JNDIHELLO");
          HelloHome home = (HelloHome)javax.rmi.PortableRemoteObject.narrow(
          obj,HelloHome.class
          Hello hello = home.create();
          System.out.println(hello.hello());
I'm running j2ee.bat that came with the sun-package.
The error I get is:

I'm completely stuck here :-( please help !!!
It's realy a pain in the ass when you try to figure something out while following a book and then when things just don't work :-(((
I've been googling for hours and I can't find anything that would solve my problem.
Hope somebody can give me some advice, would be very much appreciated.
Thanks alot !!!!!
