I can't (won't) help with a working example, but this is what you have to do:

1. Your EJBs (session beans) must be configured in a way to support remote access, RMI.
2. You have to export your EJB client classes into a separate JAR file; those are the interfaces and base classes required to perform an RMI call (stubs). This is required as clients (your WAR) must understand how to deserialize/serialize the RMI communication between your servlets and the remote EJBs.
3. Make the exported EJB client JAR available to your WAR file
4. Define an initial context pointing to your remote EJB server as described here.
5. Deploy and run it...

BTW: A personal opinion, RMI communication is painful and you should try to avoid it as it tightly couples the client (your WAR) to the remote EJBs.

EDIT: Which EJB version and which IDE do you use?
