Can you check if the server is intialized properly by opening the url : "http://localhost:3000" i.e. without your controller, if it works fine, most probably you need there's some problem with your controller class.

I am not sure, what's wrong with your webrick server, but I would suggest you to try switching to mongrel and see if it works fine. I am assuming your ruby installation is fine and without any issues.
you can run 'gem install mongrel' and then select the appropriate version to install the same..
hope this works..
