Removing message from a queue with a servlet

[bizz]

Hi,

I'm trying to create a servlet which enables it's users to delete messages from a queue.

My code is working when I run it as standalone but it is not working when I execute it as a servlet. (Although I do get a positive reply from my request the messages are not actually removed from the queue)

I guess there is something I should do different since it's a servlet but I'm not sure what it is.

My code:

InitialContext context = getContext();   // Same context used to send a message using a servlet - which works
QueueConnectionFactory cf = (QueueConnectionFactory)context.lookup("/ConnectionFactory");
QueueConnection connection = cf.createQueueConnection("user", "password");
connection.start();   
QueueSession session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);           
Queue managementQueue = HornetQJMSClient.createQueue("hornetq.management");
QueueRequestor requestor = new QueueRequestor(session, managementQueue);           
       
Message m = session.createMessage();
JMSManagementHelper.putOperationInvocation(m,
                "jms.queue.myQueue",
                "removeMessages", filter);
Message reply = requestor.request(m);
boolean success = JMSManagementHelper.hasOperationSucceeded(reply);         

result:

success is true, but the messages are still in the queue.

I'm using version 2.1.2.

I'll appreciate any help

Thanks
