Enterprise Java Beans (EJB) 3.0 is a deep overhaul and simplification of the EJB specification. EJB 3.0's goals are to simplify development, facilitate test driven development, and focus more on writing plain old java objects (POJOs) rather than on complex EJB APIs. EJB 3.0 has fully embraced Java Annotations introduced in JDK 5.0 and also simplifies the API for CMP entity beans by using Hibernate as the EJB 3.0 Java Persistence engine.
