Hello! This is my first time with RoR and web development 
I'm trying to run the "hello world" script from the book Agile Wev Development with Rails...
I've created my "SayController":
class SayController < ApplicationController   def hello   end end
and I've created my hello.rhtml with basic html that shows "Hello from Rails!".
However, when I try to access it, I get this error from the Webrick console: (I'm trying to go to http://localhost:3000/say/hello)

I don't know why it doesn't work, any idea? Thanks
