scaffold x paginate

Hi all. What am I missing here?

[output]
undefined method `paginate' for #<AdminController:0xb74bf728>
[/output]

[admin_controller.rb]
class AdminController < ApplicationController
    scaffold :product
end
[/admin_controller.rb]

$ ruby -v
ruby 1.8.6 (2007-06-07 patchlevel 36) [i686-linux]

$ rails -v
Rails 1.2.3

[WEBrick]
