Hi Guys, first of all thanks for you help. It is always good to have this kind of support. The problem is solved. The issue was: - I was using the wrong jbpm libraries - the jbpm.cfg.cml was not including the configuration property used by the persistence service | <string name="resource.hibernate.cfg.xml" value="hibernate.cfg.xml"/> Thanks a lot for your help DSE View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4245010#...
