Subject AW: Problems using openJPA

Hello Jacek,

Thanks for the prompt answer. I will send the jar as soon as possible. Unfortunately I'm at
the moment not at my used workplace.

Ignore it.

That's the culprit. Could you publish the entity jar you deployed to Geronimo. I think that
Geronimo doesn't add much to it - OpenJPA (the default JPA provider) can't do its job and
complains and so does Geronimo.
