[ale] Tomcat startup script

[Mike Millson]

I created a Tomcat startup script from a couple sources. Seems to be
working, just a couple questions.

The script references a file called  /var/run/tomcat.pid. I don't have a on
my system (RH 7.1, ver 2.4.9-21). Do I need to create it? It looks like it's
just a file w/ a # in it, the process id I gather? What process id
would/should I give tomcat?

Also, the script references /var/lock/subsys/tomcat4, another file I don't
have. What is that file for? Do I need to create it somehow?

If anyone has any suggestions for improvement, let me know. I'm basically
mimicing things I found in other startup files, not knowing all that much
what's going on.

Here is the history:
1) Installed Tomcat binaries
2) Installed Sund JDK 1.4
3) Created tomcat4 group
4) Created tomcat4 user
5) Added the following to $TOMCAT_HOME/bin/startup.sh and shutdown.sh:
JAVA_HOME=/usr/java/j2sdk1.4.0
TOMCAT_HOME=/usr/local/jakarta-tomcat-4.0.1
CLASS_PATH=.:$JAVA_HOME/lib/tools.jar
export JAVA_HOME TOMCAT_HOME CLASSPATH
6) Copied the script below to /etc/init.d/tomcat4 and did a chmod +x on it.
7) Added tomcat4 to rc.d with chkconfig --add tomcat4
