Hi Cristophe, What _exactly_ are you doing? To deploy an EAR to tomcat you copy it into the '/server/<server-config>/deploy' directory, JBoss picks up the drop, then unpacks it and its components into a '/server/<server-config>/temp/deploy'. The way to redeploy is to replace the EAR into '/server/<server-config>/deploy'. JBoss should then see the change, reploy and restart. Is this what you are doing? Also _how_ are you doing it? Are you using ant, drag and drop, or are you building it in the /deploy directory, or some other way. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3978386#...
