Web_service_dispatching_mode :layered

Hello All,
I am using layered dispatching with AWS. My controller looks like this:

web_service_dispatching_mode :layered
web_service_scaffold :invoke

web_service :user, UserService.new

Here is the part of UserService that is failing (It’s saying session
isn’t an object):

class UserService < ApplicationController
web_service_api UserApi

def login(username, password)
logged_in_user = User.login(username,password)
if logged_in_user
session[:user_id] = logged_in_user.id
return true
else
return false
end
end
end

Can you use sessions with layered dispatching? If so, how? Do I need to
require a library manually? Using sessions worked with direct
dispatching (which I believe is SOAP, rather than XML-RPC). Thanks in
advance!
