If you're seeing this page via a web browser, it means you've setup Tomcat successfully. Congratulations!
This is the default Tomcat home page. It can be found on the local filesystem at: /var/lib/tomcat8/webapps/ROOT/index.html
Tomcat8 veterans might be pleased to learn that this system instance of Tomcat is installed with CATALINA_HOME in /usr/share/tomcat8 and CATALINA_BASE in /var/lib/tomcat8 , following the rules from /usr/share/doc/tomcat8-common/RUNNING.txt.gz .
