Anyone read this ? It's a terrific book, very hands-on, practical, accurate and everything works !
It's a great introduction to JBoss and includes hands-on examples of the j2ee stack, and hibernate, jboss class loading.
I'm not the brightest, but managed to work through the whole thing in a couple of days - it's really confidence inspiring. Along with the 'JBoss, A Developers Notebook' I think it covers most of what you need to get a project going.
