This depends on what you mean by integrating. There is no ColdFusion/AEM integration piece. However - you can use a REST. That is -- you can use RestFul web service in ColdFusion - as described here: http://www.adobe.com/devnet/coldfusion/articles/restful-web-services.html to community with AEM Servlets and display AEM data in Coldfusion. Likewise - you can post data from ColdFusion to AEM using AEM Sling Post Servlets.
