We have some CMP beans that generate their own primary keys using sequence
numbers, however they aren't acquired from an external source. What is
passed into the ejbCreate methods is simply data to be stored. It never
occured to us that we were doing anything special. The big difference,
however is that the ejbCreate method must return the primary key and since
we generate it internally in the method it's there for us to return.
IMHO, sounds like BMP is what you need to use.
