Tomcat comes configured with a number of Web applications, which are reconfigured in PAS. In particular, the ROOT application that comes with Tomcat is replaced with a safe application that does not implicitly or explicitly allow access to any part of the server or other Web applications. You may replace the ROOT application at your discretion, but Tomcat requires that there always be a ROOT application.
Note: The original Tomcat ROOT application will be packaged as a WAR file and distributed in PAS's /extras directory as root.war.
