Java EE 5: The latest version of the Java Platform, Enterprise Edition Q: Whats new in the Java EE 5 platform?

• Java EE 5 accelerates and radically simplifies Enterprise Java development, especially for Web Services (JAX-WS 2.0), Web Applications (JSF), and transactional components (EJB 3.0). It introduces a new database persistence model (Java Persistence) and leverages Annotations from Java SE. • EJB 3.0 greatly simplifies the programming model through Plain Old Java Objects (POJOs), which can easily be converted to Web Services with Annotations or made persistent using the Java Persistence API. It is now much easier to write a stateless or stateful component that takes full advantage of the transactional capabilities of the EJB container. • Java Persistence is a much cleaner approach to mapping Java objects to relational databases, and benefits greatly from work done in Hibernate, TopLink, and Java Data Objects (JDO). • JAX-WS 2.0, which replaces JAX-RPC, simplifies the development of web services by automatically generating client and server code. It now provides support for JAXB 2.0 data
