title: Rabbitmq - how to listen to messages on an exchange
body: <p>I have a program in Java that sends messages to RabbitMQ. All I know is the exchange name. No queues, bindings, and so on. </p>
  
  <p>My question is this: how can I see if the program sends these successfully, knowing only the exchange name?</p>
  
  <p>Thanks.</p>
  
  <p>Regards,
