stop and start your server
or does it happen from the beginning? If so at what moment.... I do not see anything jBPM related here
Well, it happened from the beginning. I found different errors too. As follows:
ERROR [SeamLoginModule] Error invoking login method
javax.el.ELException: javax.ejb.EJBTransactionRolledbackException: exception invoking: getEntityManager
But i stop the server and start now it works fine. Can anyone tell me why this problem happens?
yes, general AS issue, not only JBoss. Happens if you deploy/undeploy a lot without restarting your AS. Totally unrelated to jBPM
Thanks a lot all of you for your valuable reply.
