------------------------------------------
[~nuno.godinhomatos] Does registering a listener with the MBeanServerDelegate help?
https://docs.oracle.com/javase/8/docs/api/javax/management/MBeanServerDelegate.html#addNotificationListener-javax.management.NotificationListener-javax.management.NotificationFilter-java.lang.Object-
There should be notifications coming through that when management ops add/remove resources. They won't be emitted until the op commits, but it's the way to get a notification when the jboss.as:deployment=foo.war mbean is created.

> -------------------------------------------------------------------------------
>
> Key: WFCORE-3387
> URL: https://issues.jboss.org/browse/WFCORE-3387
> Project: WildFly Core
> Issue Type: Bug
> Components: JMX
> Affects Versions: 3.0.8.Final
> Reporter: Nuno Godinho de Matos
> Priority: Minor
>
> In wildfly, there is a class of managed beans that are particularly useful to have available during application deployment.
> In partocular beans with Object name (e.g. jboss.as:deployment=someapp-war.war)
> This type of beans can for example sned a JMX Notification that the corresponding application has been deployed.
> While trying to refactor a mechanism that fires an "ApplicationDeployed" event, a mechanism that was blinding registering a Listener on a hard coded ObjectName stopped working consistently once I generalized to hunt for the generalized beans.
> The problem is the following.
> 1. HARD CODED APPROACH:
> If when an application is deploying, during the @Startup logic of an EJB I blindly do something like:
> {panel}
> MBeanServer mBeanServer = createMBeanServer();
> ObjectName targetObject = new ObjectName(objectName);
> mBeanServer.addNotificationListener(targetObject, listener, filter, handback);
> {panel}
> I can successfully register my Listener, without any problem.
> This will work 100% of the time, and after the deployment goes through I can send my notification to the application that the deployment is done.
> I just need to blindly register the listener on:
> jboss.as:deployment=someapp-war.war
> 2. PROBLEM - GENERALIZED APPORACH - QUERY MBEANS
> The Problem now is that once I try to generalize the mechanism, instead of directly doing something like jumping at the "registration", first I need to run a JMX query to hunt of beans:
> jboss.as:deployment=*
> Now I have the problem that I am coming out empty handed, no results.
> Better said, the current approach has two possible behaviors.
> Behavior 1 - Mechanism works:
> - Wildfly is stopped
> - on eclipse I drag and drop the WAR file to the APP server.
> - I start wildfly.
> In this case, the jboss.as:deployment=* will give me the deployed applications.
> The generic mechanism works.
> Behavior 2 - Query comes with no results
> - Wildfly is running
> - no deployments
> - I drag and drop the APP,
> then I get no results.
> Here is a Log snippet from the application when running on apporach 2.
> What you is multiple fluent wait queries.
> You have N tries loop where the query * and hard-coded object name is run. In both scenarios I get no results.
> But i still managed to register a listener If I want and I know the war name.

> I can try to create a sample application to reproduce this.
> I would expect that before the @Startup logic is triggered on any EJB, I consistenly will have on the MBean server the deployment managemend bean for the WAR whose deployment is currently ongoing - regardless of whether I start the APP serer with the WAr already in or if I have just added the WAr file.
> And in effect, since the "registration mechanims of a listener always works - if you already know the WAR file name ... then it kind means that the Managed bean is in effect in the MBean serer but somehow not visible.
> Many thanks for any help on this.
> I will try to give you a sample application for analysis.
> Kindest regards.
