Sun made my day!
The open letter from Sun regarding Java persistence is wonderful news... Sun has made public their support for creating a common persistence API underlying JDO and EJB.
Many folks, including me, have pleaded for this for quite some time, and it looks like our pleas did not fall on deaf ears.
My sincere thanks to Linda DeMichiel and Craig Russell, the
Specification Leads for JSR-220 and JSR-243.
