    Sending a SERVER_SHUTDOWN notification upon suspend

    Jesper Sigården Newbie

      Hello!

       

      I have a Wildfly-10.1.0 server that has a set of clients connected to them by means of https-remoting.

      The clients receives notifications from the server using ActiveMQ which is initiated over the https-remoting pipe on 8443.

       

      I have migrated the server from a JBoss-4.2.3 server where this functionality was implemented with a Runtime.getRuntime().addShutdownHook( ... );

      This however does not work in the Wildfly server because, well it is simply better :-)

       

      I want to send a Notification  before the server shuts down like: shutdown-signal  -> send shutdown notification -> wait 2-3 secs for clients to receive the event -> proceed with the shutdown.

       

      I have found that I could use the org.jboss.as.server.suspend.SuspendController to add OperationListener and send it on listener.suspendStarted().

       

      But how do I get hold of the SuspendController?

       

      What I have figured so far is to implement an extension to Wildfly so that I can get hold of the OperationContext and from there do context.getServiceRegistry(false).getService( SuspendController.SERVICE_NAME );

       

      Thats a ridiculous amount of code for one event.

       

      So my question: is that the only way?

       

      Can't I get the SuspendController from the JNDI, inject it into my bean or just get the service registry through some wonderful static method?

       

      Best Regards
