Not sure if this exists somewhere in JBoss, I couldn't
find it. Anyway...
Here is a little (and extremely primitive)
startup/shutdown script for RedHat systems. It assumes
that JBoss lives in /usr/local/jboss, it's run by user
'jboss' and JDK binaries are in /usr/local/jdk/bin. All
this can be changed in the script itself.
