It needs some steps to integrate OpenKM properly. Therefore, you basically need to engineer your start script yourself. The following notes should help to get JBOSS up quickly.
1) create a new user
# useradd jboss
2) copy script
# cp JBOSS_HOME/bin/jboss_init_redhat.sh /etc/init.d/jboss
3) add chkconfig properties to init file
# chkconfig: 345 65 35
# description: JBOSS AS init script
# pidfile: /var/run/jboss.pid
4) adjust all other variables in the init file header
5) add script to chkconfig
# chkconfig --add jboss
6) set jboss to be started at level 3
# chkconfig jboss --level 3 on
7) start now (# service jboss start)
