I know there is lot available on net but can we list down some noticeable (and talk-able) differences here:

1. Annotations are introduced, which makes coding so easy and now it takes less time to code EJB, Web Services etc.

2. Entity Bean is gone. Instead, JPA (Java Persistence API) is introduced for persistence.

Please add.

Thanks!

Hi !

They are *not* gone. For backward compatibility they are supported by EJB 3.0 servers too.

No, we can use Entity Bean in EJB 3.0, if we would like. Entity Bean in EJB 3.0 is the same with EJB 2.x.

Furthermore, Java EE 5 includes JSF.
