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. | Enterprise Java Beans (EJB) 3.0 is a deep overhaul and simplification of the EJB specification.

[编辑] Key Features
- Simplified EJB API
- Java Annotations
- Dependency Injection
By introducing the @Inject, @EJB, and @Resource annotations, these dependencies are now injected transparently by the container into your simple Java Beans.
- Optional Callbacks
By using such callback annotations as @PostConstruct, @PreDestroy, @PrePersist, or @PostPersist, developers can map any Java Bean or callback class method to be a callback that receives event notifications.
- Entity Manager API
Both JBoss Application Server and Hibernate support this new API.
- Simplified Persistence and Improved Queries
- Usable outside of the container!
