This describes the process for configuring Tomcat 5 on Ubuntu (or Debian) so that you can have multiple instances of Tomcat running. Typically, this would be useful when you have several domains (and/or applications) hosted on the one server and want to keep them running independantly of one another.
The general steps are based loosely on an article in LinuxJournal, however, I have added afew more explanations, corrected a couple of little inaccuracies and added new content to describe the Apache2 mechanism for loading modules and sites.
