getting remote ejb across firewall

[teknokrat]

I am trying to obtain a remote reference to an ejb in one jboss cluster from another. They are separated by a firewall. I have opened ports 1099, 4444, 1100 between them.

The normal lookup on port 1099 works ok. However, when I try to use the HAJNDI port 1100 I get that the ejb is not bound naming exception. I assumed that this was because I had to set a new RmiPort and RmiObjectPort for HAJNDI to use. So I set these to 1199 and 1144 in cluster-service.xml and opened those ports. Nothing changed.

I assume I am missing one or more ports that need opening but I can't figure out which ones from the documentation. Can someone tell me what i am missing please.

thank you

Just to provide some details. I am using jboss 4.02 and the code for getting the ejb is

Object ref = context.lookup(jndiName);
EJBHome home = (EJBHome) javax.rmi.PortableRemoteObject.narrow(ref, klass);

I have tracing on so I know that the system behind the firewall does receive the initial request on port 1100.

So why is my ejb not bound when i use hajndi?

cheers

Ok, I was being dumb. The two clusters were using the same partition name. Once I changed the names everything worked ok.
