Hi there all,
Following the Timer MBean example in chapter 13 of the online
manuals, I have a working example of the Timer MBean.
However, I'm having difficulty in getting the
"removeNotification" part to work.
I'd placed the removeNotification bit in the
stopService function ie.
public void stopService() {
_lServer.invoke(
_lTimer.getObjectName(),
"removeNotification",
new Object[]{
_efdCleanupTimer
},
new String[]{
Integer.TYPE.getName()
}
);
}
>From the MBean view (from URL://localhost:8082),
when I click on stop for this MBean,
I get the following error message.

Did I miss doing something?
Should I be overriding this function somewhere?
I've read the examples about 5 times but suspect I'm subconciously
skipping some important part everytime.
I am using JBoss 2.4.4 with Tomcat 4.0.1 on Win NT 4.0 (SP6a)
with jdk 1.3.1
Many thanks in advance,
Chai
