Re: CSE 5234 - question about EJBHome for session beans

[Rajiv Ramnath]

HI Nathan, Brandon, Steve,

Look in the **working** EJB examples given to you. The specific projects
are as follows:

* Example-EJB-Session-Entity. This project implements the session and
entity beans
* Example-EJB-Servlet. This project uses a servlet that uses the
session and entity beans implemented above.

Instructions for how to get this working are here:
