Subject RE: exception trying to stop activemq, stomp weirdness
Date Wed, 29 Sep 2010 17:22:58 GMT
Have you guys considered using something like apache jsvc to stop and start?
http://commons.apache.org/daemon/jsvc.html

It's much cleaner and doesn't require jmx to start and stop.  All that needs to be done is
to write a simple wrapper to implement the Daemon interface, and implement start and stop.

This is what I'm using to start and stop activemq instead of the start/stop scripts as we
need to drop privileges when the application is started which jsvc does.

Jsvc is supposed to work on windows (I've never monkeyed with anything but RHEL).  It starts
and stops much cleaner for my use cases.

Hi,

the stop script tries first to connect to the broker using JMX and stop it "cleanly" and if
it doesn't succeed it kills it. So make sure you enable it in your activemq.xml


Cheers
