No. The configuration we used is copied from the jpa example of the booking application. Something like this: Components.xml | ..... | <transaction:entity-transaction entity-manager="#{em}"/> | | <persistence:entity-manager-factory name="monitorDatabase" /> | | <persistence:managed-persistence-context name="em" auto-create="true" | entity-manager-factory="#{monitorDatabase}"/> | ...... And as i said, this is been working correctly so far for our application. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128159#...
