Hi! Well, firs of all let me thank you your help soumya, and your time too. I've worked with the database and the problem was there. I used an example script which came with the book to update the users (there were in the correct JBPM table). But the user I was trying to use was set as "participant" (apart from his properly TASKS group). I changed that "participant" role by "user" and it worked. My question is, how can I change the level of the role "participant" to let it logging correctly? Because I have a lot of other users, as participants, and I would like to keep them with that role, and being able to log correctly. Or if you know where I can find information It would be very useful. Thanks a lot, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4160758#...
