Inge, For development, I would use the desktop version, it starts and stops quicker. As far as the garbage collection goes, you probably won't see it with all the restarts. However, for production server, I would use the J2EE Server version. And ultimately, you might want to modify the start-up parameters to get what you want. You might want to try a profiler to see where your memory usage is at it's worst.

Now I'm not really sure what would be best for our environment. We run eclipse, jboss and tomcat on our machines, and need the most efficient environment possible for those 3 things. jboss is restarted 1 or 2 times a day, while tomcat is restarted many times a day. What would be most efficient on such a setup, a server (EE) or a client (SE) JVM?
