Hi Simon,
Thanks for your reaction.
Yes I am using JBoss 2.0 FINAL.
I am glad to hear that this bug has been fixed,
but what keeps bugging me, why didn't I get
the exception when I ran it with Oracle?
In other words can you provide me some background to
the why of this bug?
I just studied the source code and the impression
I get is that this Exception implies that I return
a null key from the beans ejbCreate(). The weird thing
is, that I have the impression that this ejbCreate() is
not actually executed. That is I have not been able to
prove (yet) that the ejbCreate code of that bean has been
executed.
So where do I go wrong?
Regards,
Cor Hofman

Are you using JBoss 2.0 ?
If so, this bug has been fixed in the current CVS.
