Hi there, If I can give you an advise, try to understand the kind of problem that EJB (3 for instance) try to solve, that will help you to understand how it works. This tutorial is available http://www.jboss.org/jbossejb3/docs/tutorial/ The is also the great book "Enterprise JavaBeans 3.0" from O'reilly. There is also the book (available in PDF for free) "The Java EE5 tutorial". Hope it will help. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4164404#...
