Thanks Martin Your comment was very helpful. In the web-console, I had indeed assigned a group (which I had defined) to my user, but I realise now that I also have to have the group "user" assigned to him as well. (I must have missed this detail in the documentation). When playing around with the predefined groups I tried to assign the group "admin" (without assigning the group "user") to my user. This causes the following error message HTTP Status 403 - Access to the requested resource has been denied after which I need to restart the system. If the group "user" is assigned to a user, everything works nicely. Greetings, Petia View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4171069#...
