Thanks for getting back to me. I think what you're describing is a env-entry for a certain web-app that can be defined in web.xml. This would then be the same for all virtual hosts that use this web app. I'm looking for a env-entry for each virtual host. So that depending on which domain name is used, a different env-entry will be listed in the java:/comp/env namespace. In Tomcat this can be configured in seperate context.xml fragments under TOMCAT_DIR/conf/Catalina/virtual-host1.com/ and TOMCAT_DIR/conf/Catalina/virtual-host1.com/ Any idea how this can be achieved under JBoss?
