Joe Rinehart has written an article for Dr. Dobb's entitled
Building RIAs on J2EE Foundations. Joe explains RIA development from a very ColdFusion and Flex centric view of the world, and walks through an example in detail. Nice job, Joe!
As a general rule, you want to be using AMF for communication between Flash Player on the client (running a Flash or Flex app) and your back-end server (unless you need messaging and push and data management services, in which case
LiveCycle Data Services is what you'll want).
Lee Brimelow explains this (and lists AMF options for different back-ends) in a recent post entitled What the hell is AMF? And James Ward demonstrates the performance implications in his Census - RIA Data Loading Benchmarks.
Long time ColdFusion/Flex/AIR/ etc. friend, Chong-Bing Liu (aka Bing) wrote an article comparing RIA trends (including Flex, Silverlight, JavaFX, and Curl) by using Google Trends. The original article is in
Chinese, and he just just posted an
English translation.
Adobe Developer Connection is running an article by Scott Stroz entitled
