Flex AJAX Bridge Source
Save this into a new S-Control named FlexAjaxBridge, it will be included by the main S-Control mentioned in the article This source came from the Adobe Labs site, under the name FAB, Flex Ajax Bridge. You will still need the Flex portion which you can get from here (as part of LiveCycle Data Services ES), this code is only the javascript portion. There is more information on the Flex Ajax Bridge here, including path information.
