Thanks -- the information helped. I've been able to store/retrieve the
CMP object successfully. I think the gap in my understanding was where
is the best place to call the create method(s) for the each CMP object
contained with another CMP object. Maybe this is heading into an
application design detail --- but --- do you think it is good practice
when you have a CMP object with CMP object references to construct the
entire object within the ejbCreate method of the top-level object?
Thanks again for the help,
Micah Skilling.
