java ee - JMS 2.0 QueueBrowser on Wildfly does not return messages -

i have 2 simple ejb beans. first 1 timer method called every second. in method add 10 random messages testqueue.

@singleton @startup public class timer {      @inject     private jmscontext context;      @resource(mappedname = "java:/jms/queue/testqueue")     private queue queue;      @schedule(hour = "*", minute = "*", second = "*/1", persistent = false)     @accesstimeout(unit = timeunit.days, value = 1)     public void addtoqueue() {         for(int = 0; i<30; i++)             context.createproducer().send(queue, "msg " + (new random().nextint(100)));         printqueuesize();     }      public void printqueuesize() {         queuebrowser qb = context.createbrowser(queue);         enumeration enumeration = null;         try {             enumeration = qb.getenumeration();         } catch (jmsexception e) {             e.printstacktrace();         }         int size = 0;         while(enumeration.hasmoreelements()) {             enumeration.nextelement();             size++;         }          system.out.println("queue size: " + size);     } } 

second bean mdb consumer. put thread.sleep(100) simulate long running task , make sure there messages in testqueue.

@messagedriven( activationconfig = {         @activationconfigproperty(propertyname = "destination", propertyvalue = "java:/jms/queue/testqueue"),         @activationconfigproperty(propertyname = "destinationtype", propertyvalue = "javax.jms.queue"),         @activationconfigproperty(propertyname = "maxsession", propertyvalue = "1") })  public class consumer implements messagelistener {      @override     public void onmessage(message msg) {         try {             thread.sleep(100);         } catch (interruptedexception e) {             e.printstacktrace();         }     } } 

the problem console output shows:

15:06:29,006 info  [stdout] (ejb default - 9) queue size: 0 15:06:30,006 info  [stdout] (ejb default - 10) queue size: 0 15:06:31,009 info  [stdout] (ejb default - 1) queue size: 0 

etc.

but in wildfly admin console can see there more , more messages every second:

the question is, why queuebrowser return empty enumeration? bug in hornetq implementation or there reason that?

although not answer question, show how queue size in hornetq, in ejb service:

    initialcontext initialcontext = null;     try {         // step 1. create initial context perform jndi lookup.         initialcontext = getcontext();          // step 2. perfom lookup on queue         queue queue = (queue) initialcontext.lookup("jmx/queue/your_queue_name");           // step 7. use jmx retrieve message counters using         // jmsqueuecontrol         objectname on = objectnamebuilder.default                 .getjmsqueueobjectname(queue.getqueuename());         jmxconnector connector = jmxconnectorfactory.connect(new jmxserviceurl("service:jmx:http-remoting-jmx://localhost:9990"), new hashmap<string, object>());//this url wildfly 8.2 (should work 8.x)         mbeanserverconnection mbsc = connector.getmbeanserverconnection();         jmsqueuecontrol queuecontrol = mbeanserverinvocationhandler.newproxyinstance(mbsc, on, jmsqueuecontrol.class, false);          // step 8. list message counters , convert them         // messagecounterinfo data structure.         string counters = queuecontrol.listmessagecounter();         messagecounterinfo messagecounter = messagecounterinfo.fromjson(counters);           queuecontrol.getconsumercount();//this returns consumer count         queuecontrol.getmessagesadded();//returns messages added last time checked         queuecontrol.ispaused();//prints out, whether queue paused (you can stop queue being processed e.g. jmx)         queuecontrol.getmessagecount();//message count far      } {         // step 17. sure close our jms resources!         if (initialcontext != null) {             initialcontext.close();         }     }
