Unit testing is great. As we learn it it's excellent. As we work on greenfield projects it's beautiful and sweet. The real problems start on the real projects.

EJB3 Tutorial part 02 – Stateless vs. Stateful

October 27th, 2009

1 comment

In the previous post we've set up our environment to work with EJB3. It's based on Eclipse, JBoss Tools and JBoss Application Server. However you can follow the tutorial with the environment set up of your choice. Another popular one would be Netbeans. You can download it as a bundle with Glassfish server. If you decide to switch it please remember that some things presented here might be environment specific and may work differently (but most of them shouldn't).

In this post we will say a little bit more about Session Beans and we will try to cover the differences between Stateless and Stateful Session Beans.

As a part of preparations for my SCBCD exam I will try to present a series of tutorials on EJB3 and JPA. It will help me to test my knowledge and maybe someone else will find it useful.
