# NEVER change the init script itself:
# To change values for all services make your changes in

# To change values
for a specific service, change it here
# To create a new service
, create a link
from /etc/init.d/ to
# /etc/init.d/tomcat5 (do not copy the init script) and make a copy
of the
# /etc/sysconfig/tomcat5 file to /etc/sysconfig/ and change
# the property values so the two services won't conflict
# Register the new service in the system as usual (see chkconfig and similars)
