That looks reasonable. If you're seeing a JSONError in receiveReply then 
the server is sending back some non-json response. If you don't mind 

     alert("receive " + ajaxRequest.responseText);

in there that would give a clue (hmm, maybe this should be logged...)

The most likely way in which the server could be sending a non-JSON 
response is if you haven't installed all the prerequisites into 
RabbitMQ. http://localhost:55670/ should show a generic list page like this:

RabbitMQ Web Server
Contexts available:
* rpc
* rabbitmq_lib

If you don't see that then check everything's installed.
