Accessing Remote EJBs

Question

I am trying to access an EJB on a remote server using the following code:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
        "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL,
        "iiop://190.30.123.34:1050");
InitialContext initial = new InitialContext(env);
Context environment (Context)initial.lookup("java:comp/env");
Object ref = environment.lookup("ejb/lands.mc.bus.TopoMap");
home = (TopoMapHome) PortableRemoteObject.narrow(ref, TopoMapHome.class);I have the following entry in my web.xml:
<ejb-ref>
<ejb-ref-name>ejb/lands.mc.bus.TopoMap</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<home>lands.mc.bus.TopoMapHome</home>
<remote>lands.mc.bus.TopoMap</remote>
</ejb-ref>But when ever i perform the environment lookup, i get the following error:
javax.naming.NamingException: Cannot create resource instance
When i print out the bindings, the TopoMap binding is present.
Can anyone suggest what i might be doing wrong?
Thanks

Answer 1

Tried that, gives me this error:
javax.naming.NameNotFoundException: Name lands.mc.bus.TopoMap is not bound in this ContextIf i change
env.put(Context.PROVIDER_URL,"iiop://190.30.123.34:1050");To a non existent URL, tells me it cant connect to the ORB, so its definitly connecting properly. I also noticed that when i print out the bindings, it prints out only those that are in my web.xml file for the tomcat server, not the bindings that are on 190.30.123.34 (J2EE server).
Any other suggestions?
Thanks,
Toby
