You configure jBPM to handle the transactions: <field name="isTransactionEnabled"><true/></field> but you comment out <!-- configuration property used by persistence service impl org.jbpm.persistence.db.DbPersistenceSer | viceFactory | <string name="resource.hibernate.cfg.xml" value="hibernate.cfg.xml" /> | --> (check the comment). So my wild guess is that you need a hibernate config to make it work. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4234038#...
