Thanks Bruce. My config is like yours and /etc/hosts also fine. I am now writing my own consumer and having some problem....i get "null" message.
My producer is http post, admin page correctly shows the message but having problem with consumer. I am looking in to it right now.

Do you have localhost configured in your /etc/hosts file? Also, instead of localhost, try 0.0.0.0 instead just to see if that changes the situation.
