Installing Tomcat with commons-daemon (jsvc)
Run Tomcat as a daemon
Most installation that I've seen of Tomcat is made with tomcat running as root. This could potentially be a disasters security hole. Most Linux systems only allow the root to listen to port 80...which is why many users of tomcat under Linux run tomcat as root. With jscv, the process will start off as root but later on will change owner to a user of your choice.
