it is very difficult to use CMP Entity beans with complex database schema.
we had the same problem couple of month ago. we solve this problem by using
an O/R tool to map the object model to the DB . this tool was VAP(visual age
persistence builder) it support one-to-one , one-to-many , many-to-many
associations. there are other O/R mapping tools.
we were able to finish developement in record time after the mapping.

cheers

Subject: Implementing using CMP quickly runs in to limitation...


I started to implement my system using CMP Entity Beans.  However, the
minute I needed to execute a JOIN in order to implement one of the finder
methods, I realized that I have a problem.  It seems, that CMP is only good
for TRIVIAL object relationships.  The minute a query needs to JOIN from
more than one table in order to execute the find, CMP shows it's
limitations.  This means, that for all but the simplest of objects, I need
to use BMP (which appears to be much slower).  Is this what most of you have
found?  Am I missing something when it comes to CMP?

Thanks.
