AFAIK, Sun is not promoting one over the other. It's really a decision
to be made by the developer. BMPs could certainly make use of JDO. But,
IMHO, CMP and JDO, albeit similar in focus, are each viable alternatives
to one another. The real difference is community acceptance. JDO still
has a long way to go to catch up to CMP as far as acceptance.
