How to stop a javax.management.timer.Timer when EJB application is undeployed

[Torben Vesterager]

Why the ** ** doesn't the EJB container stop these Timers? In my case its WebLogic 7 SP2.

Well, I'll answer it myself, so that other poor souls know how to do it:

            NotificationFilter deployFilter = new NotificationFilter() {
                public boolean isNotificationEnabled( Notification notification) {
                    if( notification instanceof DeploymentNotification)
                        return true;
                    else
                        return false;
                }
            };
            MBeanHome home = (MBeanHome) context.lookup( MBeanHome.ADMIN_JNDI_NAME);
            Iterator i = home.getMBeansByClass( AdminMBean.class).iterator();
            while( i.hasNext()) {
                AdminMBean mBean = (AdminMBean) i.next();
                if( mBean.getName().indexOf( "<APP_NAME>") != -1 &&
                    mBean instanceof ApplicationMBean) {
                    mBean.addNotificationListener( this, deployFilter, null);
                }
            }
...
    public void handleNotification( Notification notification, Object o) {
        if( notification instanceof DeploymentNotification) {
            DeploymentNotification not = (DeploymentNotification) notification;
            if( DeploymentNotification.DEACTIVATING.equals( not.getType())) {
                // do something like it ain't no thang

Remember this is a WebLogic-specific solution, and if you're running in a clustered environment you also have to consider the server name.
