The -Xrs switch did the trick - thanks Christer :-)

JBoss complains at startup about not being able to add a shutdown hook, but that is presumably exactly what is intended:

Just for the record: This was with JBoss 2.4.4, JDK 1.3.1_b24, and a standard Solaris 2.8 installation.

Darn I just spent all day trying to stop JBoss shutting down
(on Solaris again!). All combinations of nohup and & and redirections would not stop JBoss dying. Even if it was in the background typing CTRL-C in the terminal to stop any other process would also kill it!!!

My solution below for a bit of variety was to edit the run.sh file and replace
exec $JAVA .......

with

perl -e 'setpgrp(); exec @ARGV;' $JAVA ......

This makes it a leader of its process group and detaches it from the terminal. And for good measure you can tag

</dev/null 2>&1 >/dev/null &

on the end of the line.

HTH

guys,

can you post some of this to the FAQ? at least the '-Xrs' switch seems interesting (I had no idea it existed!)

[lordy]

I haven't tested but wouldnt using -Xrs switch stop JBoss
shutting down nicely if someone types 'kill PID' ???

Done.

Just did a quick test. -Xrs stops a clean shutdown from a kill signal but the shutdown.sh still works OK.

The perl setpgrp() works OK for a kill PID (and I'm assuming a shutdown.sh too )

But worryingly I've just noticed, that JBoss is stopping my web application dead in its tracks and not allowing it to shut down gracefully like JRun was. I have two servlets doing a lot of administrative stuff and they need to be shut down cleanly by the server. Any Ideas ?

Guys & Gals,

I know its in the FAQ but using java -Xrs stops JBoss 3.0.2 shutting down properly from a kill signal. (thought it still works OK from shutdown.sh).

The perl "setpgrp" thingy works better in this respect. Maybey I just want my name in lights but I think the FAQ should point this out :)

[This all seems to be a Solaris issue BTW]
