Rails Hosting Problem

Hi there, I have recently created my first Rails application and I am trying to get it online, I have all the files on the server and I have changed to production mode, I have updated the gems that were needed for the host.The problem I am having is, I keep getting a 404 error? I cannot figure out what lines of code I would need to change to get it running? anybody have any ideas?

My routes.rb file reads:

ActionController::Routing::Routes.draw do |map|   # The priority is based upon order of creation: first created -> highest priority.

  # Sample of regular route:   # map.connect 'products/:id', :controller => 'catalog', :action => 'view'   # Keep in mind you can assign values other than :controller and :action

  # Sample of named route:   # map.purchase 'products/:id/purchase', :controller => 'catalog', :action => 'purchase'   # This route can be invoked with purchase_url(:id => product.id)

  # You can have the root of your site routed by hooking up ''   # -- just remember to delete public/index.html.   # map.connect '', :controller => "welcome"

  # Allow downloading Web Service WSDL as a file with an extension   # instead of a file named 'wsdl'   map.connect ':controller/service.wsdl', :action => 'wsdl'

  # Install the default route as the lowest priority.   map.connect ':controller/:action/:id.:format'   map.connect ':controller/:action/:id' end

Thank You, Dave

Your routes.rb file isn't the problem if you get a normal 404 error. What's your .htaccess file look like, and where is it?
