Take a test drive on an open source Enterprise JavaBean server.

Whether you have been developing in Java for a few years now or are just starting out, there is no doubt you’ve become acquainted with Enterprise JavaBeans (EJBs). As an AS/400 professional, you might be resigned to the idea that you’ll have to use IBM’s WebSphere to take advantage of EJBs.

First, I’ll discuss some fundamental EJB concepts, and then I will walk through an example that can be applied to either of the two open source EJB containers (container being the proper term for an EJB server) covered in this article: JOnAS and jBoss.

Use CODE/400 to shift your server development into overdrive.
