About Using the Tomcat Manager

Tomcat distribution includes manager web application.

A default user with the user name tomcat and password tomcat is created during installation. It belongs to the roles manager-gui, manager-status, manager-script, and manager-jmx.

For information on using the manager app, see the Apache Tomcat documentation, available at the Apache’s website.

Caution: Tomcat’s manager application are installed in the ROOT webapps directory. When a component explicitly defines an application to be a ROOT context application by setting the ROOT_CONTEXT_WEBAPP variable, that application deletes and overwrites the default ROOT directory. The following warning is logged when a component deletes the ROOT application directory:
"WARNING: [TomcatContainer] Webapp directory ROOT already exists, it will be overwritten with <ROOT_CONTEXT_WEBAPP> as the root context"
