Why is consumer not created for ActiveMQ Temp Queue?

Question

Except SimpleMessageListenerContainer option, the consumer is not created for temp queue. I will not use SimpleMessageListenerContainer for some issues faced here.

Following code is not working...(even the temp queue is not created)

                        using (IConnection connection = connectionFactory.CreateConnection())
                    using (ISession session = connection.CreateSession())
                    {
                        IDestination destination = SessionUtil.GetDestination(session, aQueueName);
                        var replyDestination = session.CreateTemporaryQueue();

                        // Create a consumer and producer
                        using (IMessageProducer producer = session.CreateProducer(destination))
                        {
                            // Start the connection so that messages will be processed.
                            connection.Start();

                            IBytesMessage request = session.CreateBytesMessage(aMsg);
                            request.NMSReplyTo = replyDestination;

                            IMessageConsumer consumer = session.CreateConsumer(replyDestination);
                            consumer.Listener += new MessageListener(this.OnAckRecieved);

                            // Send a message
                            producer.Send(request);
                            ack = this.autoEvent.WaitOne(this.msgConsumeTimeOut, true);

                            consumer.Close();
                            consumer.Dispose();
                            ConnectionFactoryUtils.GetTargetSession(session).DeleteDestination(replyDestination);
                        }
                        connection.Close();
                        session.Close();

Flollowing code is working:-but the queue seems to be a persistent queue not a temp queue

                        using (IConnection connection = connectionFactory.CreateConnection())
                    using (ISession session = connection.CreateSession())
                    {
                        IDestination destination = SessionUtil.GetDestination(session, aQueueName);
                        var replyDestination = session.CreateTemporaryQueue();

                        // Create a consumer and producer
                        using (IMessageProducer producer = session.CreateProducer(destination))
                        {
                            // Start the connection so that messages will be processed.
                            connection.Start();

                            IBytesMessage request = session.CreateBytesMessage(aMsg);
                            request.NMSReplyTo = replyDestination;

                            IDestination tempDestination = this.destinationResolver.ResolveDestinationName(session, request.NMSReplyTo.ToString());
                            IMessageConsumer consumer = session.CreateConsumer(tempDestination);
                            consumer.Listener += new MessageListener(this.OnAckRecieved);

                            // Send a message
                            producer.Send(request);
                            ack = this.autoEvent.WaitOne(this.msgConsumeTimeOut, true);

                            consumer.Close();
                            consumer.Dispose();
                            ConnectionFactoryUtils.GetTargetSession(session).DeleteDestination(tempDestination);
                        }
                        connection.Close();
                        session.Close();

With the above code(with use of NmsDestinationAccessor) it is working.but it creates a persistent queue. So when i use the temp queue reply destination directly,it is not working.

1. Rather than using C#, write the code in java as it is a best suite for ActiveMQ. Read here for examples using temp queue in java.
2. And then Compile it to a JAR file and you can import it in your c# code via IKVM.NET as described here
3. Hope it will work with this.

Note: You must know that you can not use temperory queue in different session.
