Re: Network of Brokers - Connected but messages are not received on second broker

[rockies]

I am using the java classes from ActiveMQ
apache-activemq-5.14.1\examples\openwire\java Publisher and Listener. 

Modified Listener code to use Queue foo.bar on 61616 , and on  Publisher
queue foo.bar at 63616:


Web Console at 61616 shows :

Name  Number Of Pending Messages  Number Of Consumers  Messages Enqueued 
Messages Dequeued        
foo.bar 0                                         0                             
          
10001               10001


Web Console at 63616 also shows the same :

foo.bar 0       0       10001   10001

I see network connection from localhost: 61616 to localhost:63616
(broker1Tobroker2) Does this mean they are successfully networked? How come
messages are not distributed evenly between brokers?
