JBoss is an open source application server which you can start using. There are many others servers too. The current versions of JBoss support EJB3.
which way is better to go...start off with EJB 3 or graduate from EJB 2 to EJB 3...
My personal opinion is that its better to start off with EJB 2 and then move to EJB 3. Once you are familiar with EJB 2, moving to EJB 3 will not be a big deal, even though EJB 3 has some drastic changes.
