EJB 3.0 and New Java Persistence API

The new EJB 3.0 spec (JSR-220) offers some great improvements over the prior EJB specs in terms of development simplicity and new features. In this session we will take a look at the new EJB 3.0 spec and the new Java Persistence API. Included in this session will be a discussion about Java metadata annotations, simplification of enterprise beans (session and message-driven beans), interceptors, changes in transaction processing, and how the new Java Persistence API works. During the session I will be demonstrating how the EJB 3.0 spec differs from the EJB 2.1 spec through code example comparisons. I will also be discussing how the new Java Persistence API compares to related Java persistence options and whether we should be excited about the new persistence API or (yawn) sticking with what we have.
