Keep smiling :)

AJAX can be so simple with just Mongrel (no Rails required at all!!!!!):

require 'rubygems'
require 'mongrel'
require 'json'

class AjaxHandler < Mongrel::HttpHandler
   def process(req, res)
     res.start(200) do |header, out|
       out << JSON.dump({"Hello" => "AJAX!"})
     end
   end
end

Mongrel::Configurator.new :host => '127.0.0.1' do
   listener :port => 5000 do
     uri '/', :handler => AjaxHandler.new
     run
     join
   end
end


All you need are the 'json' and 'mongrel' gems. In your HTML page simply use 
jquery (www.jquery.com), and make a AJAX call to the server. That's so easy!
