Sun has released a letter to the community aiming to consolidate the EJB3.0 and JDO2.0 current efforts to produce one common POJO-based persistence mechanism for J2SE and J2EE.
The letter sounds like JDO2.0 is going to be brought inline to be more compatible with EJB3.0 persistence api, and also allow for EJB3.0’s persistence implementation to be used outside of a J2EE container.
This sounds like a great move forward.
