Hi, not really the same question. In fact the other post is based on the exception. This one is more general, not exception focused. While searching for data about the other post, i found out that there were lots of implications behind the use of persistence in jbpm. im beginning to wonder about that transaction manager not running and the use of hibernate.cfg.xml. Personnaly i put that file in the jbpm-configs.jar in the ear but apparently it is not found. What do you think about it ? Regards, O.M.
