Hello again,

after trying to establich a database connection i get the error i got before when using ClientBean/remote.

This is my source code:
Hashtable env = new Hashtable();
  |         env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
  |         env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
  |         env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
  |         
  |         final Context ic = new InitialContext(env);
  |         ClientRemote client = (ClientRemote)ic.lookup("ClientBean/remote");
  |         System.out.println("ClientBean is bound to: " + client);
  |         TemControlClient test = client.getClient(1);
  |         System.out.println("getClient returns: " + test);
  |         test = client.getClient(3);
  |         System.out.println("getClient returns: " + test);

and this is the output i got:

Exception in thread "main" javax.naming.NameNotFoundException: remote not bound

        at com.planetactive.ejb.client.Main.main(Main.java:42)
Java Result: 1

The exception is thrwon in this line:

ClientRemote client = (ClientRemote)ic.lookup("ClientBean/remote");

So i think my program can`t find the JNDI Name.

Thnks for your help in advance.
