Users installing EWS tomcat5 by RHN can install tomcat5-admin-webapps; however, the zip version just installs webapps/ROOT/admin/index.html with this message:
"Tomcat's administration web application is no longer installed by default. Download and install the "admin" package to use it."
This is consistent with the apache.org tomcat distro, where the admin application is now a separate download; however, it is inconsistent with the rpm install.
The admin application is officially supported so it should be included with the zip distro.
