...and the receiver code is:

            Channel channel = conn.createChannel();
            int ticket = channel.accessRequest("/data");

            while (!doStop) {
                boolean noAck = false;
                GetResponse response = channel.basicGet(ticket,

                if (response == null) {

                } else {

                        if (count % 1000 == 0) {

                        }
                    }
                    AMQP.BasicProperties props = response.getProps();
                    byte[] body = response.getBody();
                    long deliveryTag =

                    //channel.basicAck(deliveryTag, false);
                }
            }
        }
        catch (IOException ex) {
            ex.printStackTrace();
        }
    }
