I did not find an RPM either, and decided to add tomcat semi-manually. 
By "semi" I mean I wanted to use stock distributions of Java and tomcat 
and have some nice scripts that would get this running at boot time, 
play by the WBEL rules and be general enough to be useful for later 
releases of tomcat and the Sun JDK.

I have included my scripts and a README file; all whipped up just now 
and for my project's internal use so please excuse the terseness. Still, 
hopefully someone might find them somewhat useful.


Prerequisites
=============

A working JDK, mine is from Sun, and the latest tomcat tar ball unpacked 
somewhere, in my case /opt/. A special tomcat user ("tomcat") added to 
the system and all files tomcat belonging to this user.


Procedure
=========

Check the "tomcat.sysconfig" script for sanity and then run the 
"install.tomcat" script. After this try

	/etc/init.d/tomcat start

for laughs... :-)


Covering my posterior
=====================

This works at my site but YMMV.



Cheers!

LOCALLY ADDED OR CHANGED FILES FOR THE WBEL DISTRIBUTION


tomcat
=====

Installation

Download the latest tomcat release from http://jakarta.apache.org/tomcat/ and
install it somewhere, typically in /opt/

Edit the tomcat.sysconfig file to reflect the state of your system and then
run install.tomcat to copy the files and install the service.


Known bugs

The PID is not really saved as it should which means that the Service
Configuration application gets confused. Still, the program runs and
functions as expected so there you are... :-)
