[rules-users] Drools flow web console (5.1.M1) deployment in JBoss

[Kris Verlaenen]

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.
