Hi,
I solved this problem by creating the table with a normal integer as the
primary key and then writing a AutoNumberBean. The AutoNumberBean is
another CMP bean which just keeps track of an Integer per table. If you
want I can send you the code for it as well.

Is this listing everything that is supposed to be in my /jboss/lib

existing files, others are new:

Something just occured to me as I was working on this. Do you close the

When you have ejb-ref's you will also need a

The JBoss issue is two-fold:

timeout
2) When you cannot restart jBoss because when jBoss

your lookup is wrong. assuming you have a resource reference in your
