I want to write an init.d script with the typical start - stop options to start JBossAS. I want to use the method of writing a pid file when started and killing the pid found in the file when stopping.

I do not want to use the "normal" shutdown mechanism to stop it because that assumes the JBoss instance has exposed its remote MBean interface (and I do not want to assume that). Plus, I want to ensure it is killed, and using the "kill" command is as fool-proof as I need it to be.

I also want to be able to use run.sh to start the instance (I do not want to have to do all the work run.sh does - setting up the JVM, passing in arguments, worrying about all the cygwin - darwin things, etc. etc.).

But, if my init.d script starts run.sh, I cannot use $! in my init.d script as the pid file contents because $! is the pid of run.sh script process. It is NOT the pid of the JBoss JVM instance itself. If I then go to kill the run.sh process, it dies, but the JVM process does not. Therefore, the init.d stop option does not work - it cannot stop the JBoss VM.

I would like to propose to make the following change to run.sh that would facilitate this. This change is backwards compatible. What this change does is - if I set the environment variable "LAUNCH_JBOSS_IN_BACKGROUND" and source run.sh, run.sh will export JBOSS_PID as the pid value of the JVM process. My init.d script (the thing that sources run.sh) will be able to write JBOSS_PID anywhere I want and thus later be able to use it to kill the JBoss VM.

See attached patch for the change.
