Well, the x-dead-letter-exchange argument takes... an exchange, not a 
channel name. You need to declare another exchange to dead letter 
messages to, then a queue to consume the dead-lettered messages from, 
bind the two, then consume from that.

I'm also not sure I'd call a queue "errorXchange", might be confusing.

Finally, you have set "expires" on your queue - this will cause it to 
delete itself after 6 seconds of inactivity. I doubt you want that.

If you haven't read the tutorials I would do so - 
http://www.rabbitmq.com/getstarted.html. And of course see also 
http://www.rabbitmq.com/ttl.html and http://www.rabbitmq.com/dlx.html
