Ok thank you very much for the reply. I will take a look at your link and then come back if I have any new question. I have to tell that I am wondering why you are speaking of Jboss AS 4 and Jboss AS 5. Theorically the 5th version should be better, shouldn't it? Or are there some points that make the previous version better for some usages?
