Go here:
http://www.sun.com/training/catalog/courses/CX-310-052.xml
and read Section 4. Here it is again for easier reading. Notice the second point mentions JPA (only available since EJB3 was released), but if that doesn't completely convince you, see that the last point explicitly mentions EJB3.
Good luck!
