#NAME
# deploy2jboss.sh - deploy CCM webapps under JBoss AS 4.0.5 4.2.0
#
#SYNOPSIS
# deploy2jboss.sh [--force] service_name [source_server_configuration]"
#
#DESCRIPTION
#   jbossas RPM/Red Hat Application Stack (JBOSS_HOME not set)
#       Creates new SysV service and JBoss AS server configuration based on
#       source JBoss server configuration ( 'default' if not specified ).
#   If JBOSS_HOME is set, normal JBoss installation is assumed
#   and shell startup script is created in $JBOSS_HOME/bin

# Requires: getopt sed jar java
