You really should take a look at some of the other ORM packages
available.  Hibernate is a good place to start:

www.hibernate.org

Here's a nice discussion on JDO vs. EJB/CMP:

And there's another great place for discussing persistence here:

I'm in no way an expert on this stuff.  I suggest you take your time to
do some homework, read the threads.  I like to use Google and search on
things like "EJB vs. JDO" or "EJB nightmares" or "Hibernate problems"
and find out what people really think.

I don't mean to completely diss the EJB architecture; there are benefits
to EJB for some sites like Amazon.com, where they may have failover
among dozens of machines.  That might be what Dieter refers to as
"scalability".  But for single-machine use (as is typical on an
iSeries), the EJB model is definitely overkill.
