With that you could do a one command restart. +1 Sudo can be configured to allow a single user the ability to run a single command as another user. So you set up a user called tomcat_restart and give them a single command they can execute via sudo: sudo -u tomcat_user /path/to/restart_script.sh >> Is there any other way to programatially stop/start comcat? > > There's the shutdown port (or perhaps System.exit() called from an > app), but that's just to stop Tomcat.
