Some New Features in Java EE 6
- Was focused in making the Java EE platform light weight and making the environment easier for the developers
- Introduced new APIs such as WebBeans 1.0
- Made servlet technologies to be more matured
- Started to prune APIs that are not used much or not essential or better options are available or technologies have shifted. It’s also an effort to make the platform light weight
- APIs under considerations for Pruning
- JAX-RPC [Better option: JAX-WS]
- EJB 2.x Entity Beans [Better option: POJO based JPA and EJB 3]
- JAXR – the adoption was very limited
- Java EE Application Deployment and Management : As did not get much vendor support
- Introduced the concept of profiles. As the full Java EE stack may not be required for all applications, profiles use subsets of APIs geared towards a particular type of applications [making the stack lightweight].
- Web profile contains the APIs: Webbeans 1.0, EJB 3.1 (Lite), EJB 3.1 (full), JPA 2.0, JTA 1.1
- In Java EE 6, JPA is completely separated from EJB and has become distinct API in its own right
