Yes, somebody has ever tried to start a process in the background. The problem is, it will foreground if it requires tty input. An interactive shell will thus foreground when it wants to read input. If you disable that, you can run it in the background just fine.

Code:
sh </dev/null &

(It finishes pretty quickly because it has nothing to do, though. :^)

Servers usually have their own start-up scripts which often require root privileges. Depending on your architecture, look for something like /etc/init.d/tomcat (for a Debian-type system) or /etc/rc/tomcat or some such.
