We've noticed that the class not found error (during
the createEntityContainer() code as per
my original note) occurs shortly after
a "sealing violation" on a jar ?
A redeploy of the jar, to hopefully correct
the sealing violation results in the class not
found errors for any EJB - including the gangster
CMP examples !
Hmm. Judging by the lack of responses, this is
only happening to us!?
