all service does it to run a script found in /etc/init.d
(or /etc/rc.d/init.d on older systems). So write a script
that starts and stops tomcat.
The Debian tomcat4 package comes with the following script
so it might need a bit of modification for your environment:-
f#! /bin/sh -e
#
# /etc/init.d/tomcat4 -- startup script for the Tomcat 4.0 servlet engine
#
# Written by Miquel van Smoorenburg <[EMAIL PROTECTED]>.
# Modified for Debian GNU/Linux by Ian Murdock <[EMAIL PROTECTED]>.
# Modified for Tomcat by Stefan Gybas <[EMAIL PROTECTED]>.
