# JBoss Control Script
#
# To use this script run it as root - it will switch to the specified user
#
# Here is a little (and extremely primitive) startup/shutdown script
# for RedHat systems. It assumes that JBoss lives in /usr/local/jboss,
# it's run by user 'jboss' and JDK binaries are in /usr/local/jdk/bin.
# All this can be changed in the script itself. 
#
# Either modify this script for your requirements or just ensure that
# the following variables are set correctly before calling the script.

# Source function library.
