This book explains and demonstrates the fundamentals of the EJB 3.1 and Java Per-

sistence programming models. Although EJB makes application development much

simpler, it is still a complex technology that requires a great deal of time and study to

master. This book provides a straightforward, no-nonsense explanation of the under-

lying technology, JavaTM classes and interfaces, the component model, and the runtime

behavior of EJB. It does not include material on previous versions of the specification,

however.
