[jboss-jira] [JBoss JIRA] (WFCORE-3387) MBeanServer - not returning ManagedBean jboss.as:deployment=* during deployment

MBeanServer - not returning ManagedBean jboss.as:deployment=* during deployment ------------------------------------------------------------------------------- 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. {panel} ####2017-10-27 11:44:10,171 ThreadId:512 INFO [logger: .impl.jmx.AbstractJmxAppDeploymentNotificationListenerRegistration] -

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.
