What is the difference between Public Final Draft and Public Final Draft 2 of EJB 2.0?

Robert Castaneda

Check out section E.12 of Public Final Draft 2 for a complete listing of the changes between versions.
The major changes were the addition of Local interfaces and Local Home interfaces for both Entity and Session Beans.

On the Container Managed Persistence (CMP) front, Dependant Objects (which were a source of controversy) were removed.
