# JBoss Control Script
#
# To use this script
# run it as root - it will switch to the specified user
# It loses all console output - use the log.
#
# Here is a little (and extremely primitive)
# startup/shutdown script for SuSE 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 amend this script for your requirements
# or just ensure that the following variables are set correctly
# before calling the script.
