Specifying dependencies between Scheduler MBean and Schedula

[kellyschrock]

Hi,

I would like to specify a dependency between the scheduler MBean and the Schedulable implementation I've written. I've configured the scheduler to start on server startup, and run every n minutes. However, when JBoss starts, it craps out because it can't locate the class I've specified as the Schedulable implementation it's supposed to invoke. I can get around the problem manually by touching the configuration file in $JBOSS_HOME/server/default/deploy, but that seems pretty lame. Is there a way to tell JBoss, in effect, "Don't try to start the MBean until the scheduled object is available"?

Hi,

<depends optional-attribute-name="SchedulableMBean">my:jmx=mbeanname

If you write it as an MBean rather than a class.

Alternatively, name the class in
the element.

Or, change the deployment scanner in jboss-service.xml
to the prefix version and change the names of the files
to something like:

10-mySchedulable.jar
20-scheduler-service.xml

The first option works the best, the others are mainly
start-up orderings that aren't useful for a redeploy.

Regards,
Adrian

Sorry that should read

Alternatively, name the class's jar in
the element.
