CMP and BMP in EJB 3.0

[Ravi kanth P M]

Hi Friends,
I did not find any references to CMP or BMP in EJB 3.0. Are there concepts obsolete now, since we are using Java Persistence concepts? Can someone please educate me on how this can be achieved using Entity Beans in EJB 3.0?

CMP and BMP is a EJB2.x notion for entity beans. In JPA, there is no such notion for Entities.
