Hi Thomas, thanks for your answer. I've already assumed that there's no other option to obtain the user Id (yes, I mean the number and in my specific case I cannot use the name) than to use the "UserModule". Unfortunately, the UserModule don't work as I use a java bean in the same application (and java beans and UserModule don't harmonize in a managed transaction). -> http://www.dbforums.com/archive/index.php/t-1078951.html Greetings, Mac View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4034935#...
