Tomcat 4 management scripts, multiple instances and configuration

[Martin Stafford <ma...@spike.com.au>]

Here's some scripts I've written to manage multiple tomcat instances on our
Linux development server. It does the following things:
o Allows management of multiple instances
o Sends tomcat output to syslog so that it can be broadcast to development
workstations (they listen with netcat - nc.exe -l -u -p 514)
o Waits for tomcat to shutdown before restarting it

CATALINA_HOME should point to the location that you extracted tomcat to. I
use /usr/tomcat

CATALINA_BASE should point to a location containing unique copies of:
conf
work
logs
webapps
Your webapps could live somewhere else but I leave them there to keep all
the files for one instance together.
All of the ports listed in each $CATALINA_BASE/conf/server.xml must be
unique such as your warp listener, server port etc.
