I refer to the following link to setup JBOSS run as a service. 
http://www.jboss.org/community/docs/DOC-12305
How do I Start JBoss on boot with Linux?

I tried both script on this page and the one under jboss-4.0.5.GA/bin/jboss_init_redhat.sh. When I do (ps -ef | grep jboss), no process shows up. I would be really appreciate if someone can give me some advice.
Thanks,
Below is my script. I masked the ip address. 

#!/bin/sh

JBOSS_HOME=${JBOSS_HOME:-"/srv/caGrid/lsd/apps/ncia4/jboss-4.0.5.GA/"}

#define the user under which jboss will run, or use 'RUNASIS' to run as the current user
JBOSS_USER=${JBOSS_USER:-"jboss"}

#make sure java is in your path
#JAVAPTH=${JAVAPTH:-"/usr/java/jdk1.5.0_16/bin"}
JAVAPTH=${JAVAPTH:-"$JAVA_HOME/bin"}

#configuration to use, usually one of 'minimal', 'default', 'all'
JBOSS_CONF=${JBOSS_CONF:-"default"}

#bind address for jboss services, by default bind to *all* NICs
JBOSS_HOST=${JBOSS_HOST:-"140.xxx.xxx.xx"}

#define the classpath for the shutdown class
JBOSSCP=${JBOSSCP:-"$JBOSS_HOME/bin/shutdown.jar:$JBOSS_HOME/client/jnet.jar"}
#define the script to use to start jboss

#define what will be done with the console log
JBOSS_CONSOLE=${JBOSS_CONSOLE:-"$JBOSS_HOME/log/jboss.log"}
echo $JBOSS_CONSOLE

JBOSS_CMD_START="cd $JBOSS_HOME/bin; $JBOSSSH"
