Can anyone help me determine the compatibility of having non-JBoss J2EE servers connect to JBoss EJBs remotely, including what it took to get to work? Currently, I tested WebSphere 5 successfully, with the following requirements identified:

- Had to define INITIAL_FACTOR: table.put( Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");

- Had to include jbossall-client.jar in WebSphere's classpath.

Can anyone tell me if this is all that was needed on WebLogic? What about WebSphere 4? Other J2EE containers?

Basically, I've created a J2EE centrally managed application security service that deploys on JBoss (http://as.JoshuaBranch.com), but is designed to support client applications on other J2EE servers. I can only attest today though that it works with JBoss and WebSphere client applications. It's very difficult, costly and time consuming to get involved in testing all the other vendors today; so, any help of any kind is very appreciated. :)
