I set up a jboss 4.0.3SP1 AS with the jboss portal 2.0.1RC3 and the jboss wiki and all works fine. Now i want to upgrade my portal to version 2.2.1RC3 is this possible and will jboss wiki work? What I have to do that Wiki will work? And my 3rd question is, is it possible in jboss wiki to make roles which have only access to certain entries in my wiki?
