[fedora-java] Packaging tomcat shell scripts

[Robert Rati]

Here's a listing of the directory structure hadoop and similar bits 
produce in their builds:

There's a some stuff in there that's can obviously be paired down. 
Here's the script used to start/stop the service:

It should be noted that upstream hadoop, and its ecosystem, use tomcat 
6.x and as part of packaging it we've moved forward to tomcat 7.x.
