# JBoss AS7* Control Script
#
# ** Modification for AS7 server made by ArtCom GmbH 2011/10/22 **
#
# 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 Ubuntu systems. It assumes 
# that JBoss-AS7 lives in /opt/jboss-as7, it's run by user 
# 'jboss' and JDK binaries are in /usr/java/jdk/bin.
# All this can be changed in the script itself. 
# --------------------------------------------------------------------------
# See also the specification here:
# http://refspecs.freestandards.org/LSB_3.1.0/LSB-Core-generic/LSB-Core-generic/iniscrptact.html
# Summary: Required subcommands:
#    start, stop, restart, status, force-reload
# The Subcommand status must provide the following exit codes:
# 0	program is running or service is OK
# 1	program is dead and /var/run pid file exists
# 2	program is dead and /var/lock lock file exists
# 3	program is not running
# 4	program or service status is unknown
# --------------------------------------------------------------------------

# Either amend this script for your requirements
# or just ensure that the following variables are set correctly 
# before calling the script
