I have JBoss 4.0.4 installed on a Linux box. It is running behind a firewall with NAT. It has its own private IP address non-addressable from outside - very typical. I searched and found some document regardingt to set -Djava.rmi.server.hostname to the public IP address of the server when starting JBoss server. The client, using EJB3, can create an initial context to the server without problem. But the first lookup through the context will fail. The client console indidcate that it is trying to access InvokerLocator at socket://x.x.x.x:3873. The x.x.x.x is the private IP address of the server not accessible from outside. So the call will fail. The 3873 is defined in deploy/ejb3.deploy/META-INF/jboss-service.xml with socket://${jboss.bind.address}:3873 Apparently, it is bound to the private IP address. But I can't change it to the public IP address since the public IP address is a NAT through the firewall and is not valid in the server box. What do I need to do to return the public IP address to the client and at the same time be able to start InvokerLocator using the private IP address? I have the -Djava.rmi.server.useLocalHostname=false. It does not seem to make a difference true or false. I don't think it matter in my case.
