Yes, it is true that there are major differences between EJB 2.x and EJB 3. But it will take some time for the industry to adopt to this new EJB version after which EJB 3 will be the new standard. [ September 06, 2008: Message edited by: Jothi Shankar Kumar Sankararaj ]

Did a rm -R / to find out that I lost my entire Linux installation!
The problem is there are very few vendors that support EJB3 yet. IBM just came out with WebSphere 7 beta. When it goes GA, and IBM clients start adopting it (Banks and Insurance Companies, which do not like to be leading edge), then you'll see alot more EJB3.0 out there.
