Here a very simple init script tested on Suse SLES 10. An other good way to create one is looking at the init-Script for tomcat or using just it and installing Jira as WAR into tomcat.

#!/bin/bash
# Jira startup script
# install:
# copy to /etc/init.d/jirad
# ln -s /etc/init.d/jirad /sbin/rcmy-jirad
# insserv /etc/init.d/jirad
 
### BEGIN INIT INFO
# Provides:          jirad
# Required-Start:    $local_fs $network
# Required-Stop:
# Default-Start:     3 5
# Default-Stop:      0 1 2 6
# Short-Description: Starts Jira server
# Description:       Starts Jira Issue Tracking
### END INIT INFO
# Based on script at  http://confluence.atlassian.com/pages/viewpage.action?pageId=183148
