Hi, First off, all you need to do to respond to the OpenJPA Users mailing list is to address the e-mail with [email protected]. You can also use utilities like nabble [1] or markmail [2] for monitoring and responding to the Users and Dev mailing lists. There is more information on the various OpenJPA mailing lists on our website [3].
Back to your problem... Have you tried specifying this Common.jar via the <jar-file> element in the persistence.xml? This would tell OpenJPA where to look for referenced Entity classes. FYI, it has been our understanding that finding Entity classes via the Manifest in referenced jar files is not a spec requirement. It sounds like a "nice to have". But, let's see if we can get you running with WAS and OpenJPA.
