Java Enterprise Edition (JEE) servers

Two of the most renown JEE servers are JBoss (now under RedHat) and GlassFish (from Sun).

However, if your company is primarily using Weblogic at the corp level and you want to have a development environment, you can download it here, it comes with a free developer license (which allows up to 5 ip addresses) to perform your test and development.

Maybe it is due to my lack of knowledge of the server. I was unable to successfully create my own project using the easy start. The project was created using the wizard but failed to start. Also, I noted that the weblogic server (10.3 still uses Java 1.4 instead of Java 1.5 or Java 1.6) as used by the JBoss and Glassfish. Also, there was no easy way to start the server by itself.

I tried JBoss, starting and stopping is very simple. I have yet to try out Glassfish.

JBoss 4.2.x is JEE 5 able but not certified. JBoss 5.0 is JEE 5 certified. Glassfish and Weblogic also support JEE 5. All three servers are supported by NetBeans.

Understanding J2EE Programming

I have bought many books on J2ee programming and I found a lot of times the concept is very difficult to grasp - especially for a person who is from .Net programming background.

However, I found so far the best explanation to help understand the concept is from theserverside web site. The provide some complete books on the subject in PDF format for free download. One of them is Mastering EJB.

If you are interested in the subject, this is an excellent place to start. However, the book may be a little outdated but I believe most of the concepts on the stateful and stateless beans are still explained nicely in the book. There is also a more uptodate version of it (again free download of the complete pdf) - Mastering Enterprise JavaBean 3.

One of the problems I have with J2EE, is they keep adding other framework like Struts, JavaFaces, Hibernate etc. The above book does not cover those.
