Method Detail

handleNotification

public void handleNotification(javax.management.Notification n,
                               java.lang.Object o)

This is called when the full server startup has occurred, and you get the "Started in 30s:935ms" message. We load all startup classes, then initialize the plugins. Currently this is necesssary, since startup classes need to initialize the application (creating callbacks, etc.), and plugins can't hit the app until that's been done. Unfortunately, it also means that any startup listeners that depend on plugins loaded through the deployer won't work. So far that doesn't seem to be a problem, but if it ends up being one, we can split the plugin loading into more stages so that everyone has access to everyone.

MBean Service start method. This method is called when JBoss is deploying the MBean, unfortunately, the dependencies that this has with HighAvailService and with other components is such that the only thing this method does is queue up the plugins that are ready for deployment. The actual deployment occurs when the startDeployer() method is called.
