Java Persisence API in WebSphere

Starting from J2EE 5, the Java Persistence API is part of the J2EE specification. The basic idea is you develop data access application by creating POJO classes like Hibernate and then the container specific implementation takes care of interacting with the database.

The WebSphere Application Server V7.0 has support for JPA (I believe JPA 1.0) and i remember reading that WebSphere Application Server V8.0 supports JPA 2.0 and also provides second level caching. Since IBM will provide as well as support JPA i think WebSphere customer's might move towards it so i started spending some time learning about it and i am planning to blog about my experiences with JPA

The Rational Application Developer has support for developing JPA applications. You can execute JPA applications both inside and outside the container.
