Try this. Remove your war file from the deploy folder and start JBoss. Once the server has started up without any errors, place your war file in the deploy folder. See if it deploys fine. There have been issues reported about applications not getting deployed when JBoss5 is booting. Btw, the logs that you posted look like DEBUG level messages (i guess you found them in server.log?). Are you sure the application is not deployed? Did you try some functionality of the application? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138459#...
