Mike,
Following an EJB training course that I attended, I believe this problem is
being addressed in EJB spec 1.1, by allowing deferring of primary key
generation until deployment time.
I think this means that the deployment descriptor for the entity bean will
be able to specify how it gets its primary key - in a DB independant way.
Check out the EJB 1.1 spec, I would be interested to know the details
aswell !
