We are very happy to announce that the JPA 2.0 (JSR 317) specification will have its reference implementation provided by EclipseLink. This is a natural extension of our work started with TopLink Essentials in GlassFish where we delivered the reference implementation for JPA 1.0.
The feedback received on TopLink Essentials from the community has been enthusiastic. To date it’s been distributed within the GlassFish, SunAS, OracleAS, JEUS (TmaxSoft) application servers as well as being included in the Spring Framework. This has put TopLink Essentials into many developer's hands and has lead to many requests for advanced functionality--functionality that was already provided in Oracle TopLink.
With the contribution of the full functionality of Oracle TopLink into EclipseLink and its selection as the JSR 317 reference implementation included with GlassFish, we can address these feature requests from our broad community.

P.S. We will be at JavaOne where you can learn more about EclipseLink and GlassFish. We have an interesting session discussing how you can use EclipseLink with NetBeans (TS-5400: Developing Java™ Persistence API Applications with the NetBeans™ IDE and EclipseLink)
