If that script works, then great.
A less elegant way to do it would be to utilize pgrep. Do a man on it
(not sure what platform you are running on). You can pgrep for the
earliest PID that was run with a number of options. I use it for a Jserv
installation and it works quite nice.
I have not tested it with Tomcat, though.
Good luck,
