Help: JMX timer fails to undeploy when called from sar file
Hi,
I'm working on a project where I want to use JMX timers. During
startup, the application creates a timer, and I declare a Listener to
receive the events. The startup class is packaged in a sar, and the
timer in a different jar (since it's not a service).
Everything works fine, as far as the timer is concerned, and I get the
events back properly. But when I undeploy my application (on
redeployment) I sometimes (not always) get exceptions thrown (see
below) about "Error creating MBeanProxy: jboss:service=WebService".
My suspicions being on MBean dependencies, I've played around to
declare my sar file to depend on several things, including, of course,
jboss:service=WebService (see below). That actually made the
exceptions less frequent, but they still persist after about 3 or so
undeployments. After I get the exception, I need to shutdown the
server, btw, as the timer will never start properly again.
Any hints?
I'm using jboss 3.20+tomcat 4.1.24.
Thanks so much in advance,
Naomi
