I must've missed the place in the documentation where it explains how
to get Tomcat to start as root, then drop privileges after opening
listening sockets on low-numbered ports that are only accessible by
root, like Apache HTTPD does.
It's called the commons-daemon project. The linux compiled runtime of this project is jsvc.

On most Unix-alikes, you have to choose:

o  tell people to use port 8080 or whatever nonprivileged port you
   configured;

o  use a packet-mangling firewall rule to remap port 80 to port 8080
   or whatever;

o  place a proxy (such as Apache HTTPD) in front of Tomcat to forward
   port 80 traffic;

o  run Tomcat as root, allowing buggy app.s to make arbitrary changes
   anywhere on your server.

If I ever have time to do something about that, I'll be sure to submit
a patch.
