I'm guessing that you have multiple version of javax.persistence in your
classpath (one in the server war and one on the server classpath),
causing the cast to fail. Could you verify that this might be true?
If so, simply remove the duplicate persistence-api.jar from the server
war, that should fix this issue.

Thank you for the reply Kris and Satish. It really helped me to
remove the
errors from eclipse. However I still face the error when I click on
process
on web-console.

Also the Jboss server starts with some error. Can you please tell me
what
could be the reason behind this?
