Seems to me that either way could work, but point taken.  -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/610917#610917] Start a new discussion in JBoss AS7 Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
