I would like to be able to set a docBase in 4.0.2 for our web application to point to a directory where we store our application images as opposed to packaging them into a WAR. I had done this previously in 3.2.5 by modifying the server/all/deploy/jbossweb-tomcat41.sar/jboss-service.xml with the xml below, however it does not work in the jboss-service.xml for 4.0.2.

Found the solution. With 4.0.2, I had to make that modification to the server.xml in jbossweb-tomcat55.sar rather than to the jboss-service.xml.
