[rabbitmq-discuss] Help setting you RabbitMQ and testing with the C client

Tue Apr 12 14:07:27 BST 2011

Hi,

This tutorial, especially the part about exchanges, should answer most
of your questions: http://www.rabbitmq.com/tutorials/tutorial-three-java.html

The default (or nameless) exchange is special. The broker
automatically declares a binding for every queue on the server with
the binding key identical to the queue name. You don't have to (and,
apparently, you can't) do it yourself.

Regards,

Valentin.
