ABSTRACT:  EJB and JDO

The recent announcement by Sun Microsystems about the EJB and JDOspecification teams collaborating on a common persistence API was driven by requests from the Java community. The collaboration will result in the development of a new specification that incorporates the best of parts of the JDO and EJB standards. Like JDO, this common persistence API will work in and out of the container. Additionally, JDO 2.0 will continue to push forward, sharing many aspects of the new persistence specification e.g., object/relational mapping metadata, but adding functionality that will go beyond the scope of the new persistence specification. In this presentation, we will highlight the current status of the new persistence specification and the details of the JDO 2 specification.

We will highlight how developers can use the JDO specification, available today, as the perfect migration path to the new persistence specification and how products supporting both specifications can provide interoperability between the two standards. Finally, in this presentation, we will highlight criteria to look at when you evaluate different persistence solutions.
