Webservices with RoR | Urgent

Hello all,

I have to make a sample application that consumes webservices. I have been googling since morning but the examples I found either dont work, or their wsdl isnt accessible or have some problem or the other. Can anyone please direct me to a tutorial that explains in detail how to consume web services (preferrable, those that return XML) in Ruby on Rails.

Also, I found a tutorial that made use of a wsdl file. It generated 4 files using

wsdl2ruby.rb --wsdl URL --type client --classdef --force

If anyone could guide me what to do next, I mean after I have these 4 files, what do I do with them and how do I use them in my web applications
