The recently-released Enterprise Java Beans 3 improves upon the old EJB architecture by reducing its complexity from the developer's point of view. Aimed at beginning to intermediate programmers, this text uses numerous examples to introduce the main components of the EJB 3 API. Coverage includes (for example) session beans, entities, persistence features, message-driven beans, and Web services. The migration of applications from EJB 2.x to EJB 3 is also addressed.
