Question

There’s an Arquillian integration test using JMS HornetQ with persisted messages. Some test leave the messaging journal filled with unhandled messages that break other tests expecting no data.

Is there a way of telling JMS to clean its messaging journal before or after executing a test?

Answer 1

This does not exist in the JMS API itself, but there’s a method ‘removeMessages(filter)’ in the HornetQ QueueControl management object. This method can be found in the JMX Bean for the Queue, but I wouldn’t know how to get that in Arquillian.

Luckily, you can invoke management operations via the ‘hornetq.management’ queue. See http://docs.jboss.org/hornetq/2.2.5.Final/user-manual/en/html/management.html. In practice, the following should work:

     Queue managementQueue = HornetQJMSClient.createQueue("hornetq.management");
     QueueRequestor requestor = new QueueRequestor(session, managementQueue);
     Message m = session.createMessage();
     JMSManagementHelper.putOperationInvocation(m,
                                                "jms.queue.exampleQueue",
                                                "removeMessages","*");
     Message reply = requestor.request(m);
     boolean success = JMSManagementHelper.hasOperationSucceeded(reply);
