Hello,

nobody has an opinion or an advice ?

Ejb3 is very well discussed for 3 years ;)

Look at theserverside.com - source for many good discussion on JEE.

http://www.theserverside.com/search.tss?rankBy=&size=&start=&q=ejb3+vs+ejb2&dateRange=all

For me most important is testability: you can start enity factory manager in 6 seconds without server ;)

Ejb3 is backward compatible, so would advice to write only new code in ejb3, and don't rewrite your ejb2 code but only when you really need.
