I didnt' have my project desktop right here...but i'll try: The datasource is specified in you hibernate.cfg.xml. It should be JbpmDS out-of-the-box. In your weblogic-console you can add a datasource with the connection parameters to you db. In hibernate.cfg.xml you can choose between CMT and JTA transactions. I think in standard case, JTA is used. There should be something like JBossTransactionManager set--> change the word JBoss to Weblogic.
