Rails - May 2006 - web services on the client side

i am reading through chapter 20 of the agile web development book and 
trying to figure out how to use web services. i set up two different 
rails apps. one as the server and one as the client. setting up the 
server seems to work fine. but when i use the example at the end of the 
chapter to set up a client, i get the following error when i open the 
page:

Missing API definition file in apis/user_api.rb

Which is the filename for my user api on the server application. I have 
this in my controller:

class RemoteInfoController < ApplicationController
  web_client_api :user,
    :soap,
    "http://my_ip_address/server/backend/api"

  def list
    @users = user.find_all_users.map do |id|
      user.find_user_by_id(id)
    end
  end

  def index
  end
end

Am I supposed to have a user_api.rb file on the client application too, 
or have I just made a mistake?

yes, you need apis/user_api.rb and you''d provide the method signature
for the api call there with api_method

such as

  api_method find_user_by_id,
    :expects => {:id => :int},
    :returns => {:user }

please note that I am not expert in this area. For complete info, see
this HowTo article on rails site.

http://wiki.rubyonrails.com/rails/pages/How+To+Consume+.NET+WebServices

also, if you are trying to do anymore than basic web service stuff,
ActionWebService might not meet your needs, you would need to check
''soap4r''.

Hope that helps

I have not done server side WS in rails. I created just a client for
consuming a .NET service and had to put the signature in apis/api.rb.
