5:34 a.m.
I had a weird problem in deploying my application under JBOSS-4.0.5, caused
by a failure in finding an instance of Timer.
Here is an overview of what I was doing:
1) my application contains an MBean in which I inject a dependency on Timer using the
following code:
| private static final String TIMER_SERVICE_NAME =
"DefaultDomain:service=timer";
|
| private static final long TIME_GRANULARITY = Timer.ONE_MINUTE;
|
| private final MBeanServer server = MBeanServerLocator.locateJBoss();
|
| /**
| * need to put timer-service.xml in the deploy directory to make it work
| *
| * @uml.associationEnd
| */
| @Depends(TIMER_SERVICE_NAME)
| private TimerMBean timer;
|
| @Depends(TIMER_SERVICE_NAME)
| private ObjectName timerName;
|
|
2) later on in the application I add to server some Notifications in order to call
another function of the MBean
when I receive a Notification from the Timer
3) I deploy also a timer-service.xml in JBoss:
<server>
|
| <!-- ==================================================================== -->
| <!-- JMX Timer MBean -->
| <!-- ==================================================================== -->
|
| <mbean code="javax.management.timer.Timer"
name="DefaultDomain:service=timer"/>
|
| </server>
|
|
Now, the code was working, and I was able to see from the jmx-console my MBean
Then I decided I want to use jconsole from Sun java distribution, so I read some wiki
pages in JBoss
web site, and I added to $JBOSS_HOME/bin/run.conf the following line:
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote"
When I tried to deploy again my application, after restarting JBoss with the previous
options, I got the
following error when JBoss tried deploying my application:

Then I decided to check from jboss jmx-console if the Timer was there, and from the web
page I can see it...(with the correct name: DefaultDomain:service=timer)
I'm curious to understand the reason of the problem, if there is some expert that is
willing to explain it ;-)
Thanks in advance,
Andrea
