Sorry if it seemed that was implied.

My response was basically that I derive the CATALINA_HOME and other bits
based on where the install by symlinking the init script to it and then
working out where it is. Thereby doing away with the need to set a global
env at boot for the whole system and giving me the ability to run multiple
instances.

Otherwise I would (still specific and not system wide):

1) create a file in /etc/default (e.g. /etc/default/myTomcat)
2) source it in the init script

Otherwise as a global /etc/profile should do it. To test you can simply
have your script write something to a log and have a look after boot, e.g.

echo $CATALINA_HOME >> /tmp/check_env.log
