Here's the solution: Edit the web.xml in /opt/jboss-5.0.0.GA/server/default/deployers/jbossweb.deployer by adding <!-- 404 SC_NOT_FOUND --> <error-page> <error-code>404</error-code> /error/error404.html </error-page> just after </welcome-file-list> Then the html and supporting files (images, css, etc.) go in /opt/jboss-5.0.0.GA/server/default/deploy/ROOT.war/error View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203815#...
