It would be strange if we do.
What I basically see is that we start listening on the receiving
app (subscriber) as follows:
boolean durable = false;
final boolean mandatory = true;
final boolean immediate = true;
channel.exchangeDeclare(exchangeName, "direct", durable,
mandatory, immediate, new HashMap<String, Object>());
channel.queueBind(queueName, exchangeName, routingKey);
boolean noAck = true;
queueingConsumer = new QueueingConsumer(channel);
channel.basicConsume(queueName, noAck, queueingConsumer);
the sender uses
