1) If the WAR file is a new file (which wasnt deployed earlier) then just copy/paste it to the deploy folder. It will be automatically picked up by JBoss and deployed. You dont have to restart JBoss. 2) If the WAR is an already deployed application A) and it is in exploded form, then follow this : http://wiki.jboss.org/wiki/Wiki.jsp?page=RedeployAnApplicationWhenChangeA... B) If the WAR is deployed as an archive, then just delete it from the deploy folder and paste the new WAR (containing the changes you made). You dont have to restart the server, in any of these cases. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075703#...
