[rabbitmq-discuss] simple.publish over the JSON RPC interface

Mon Aug 3 08:51:12 BST 2009

Hi,

You must re-check exchange type of it (this is a topic exchange) and
consumer code (make exchange/queue, and bind exchange with queue).

* gen_server make proc cast for a long time and until timeout it will arise
error {error, timeout}.
