I already answered that question. You will note that in my original answer I gave three possible solutions: 1) Copy JBoss AS again 2) Apply the fix to the new JBoss AS installation 3) Use a tools to sync the changes from the old, hotfixed, JBoss AS to the new one Use whichever method you are most comfortable with, or is the easiest for you. I am making that assumption that your application is deployed in the JBoss AS directory structure. Another thought - does your application use the hsqldb database? I hope not, but if it does, options 1 or 3 are the best bets. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4207551#...
