I have a Coldfusion server set up in "Server" mode (as opposed to "Multiserver") running through IIS. Following the procedures outlined in the Adobe Technote, I've attempted to integrate Flex with CF, but with no success. I get HTTP 500 errors whenever I try to browse an mxml file. Does CF have to be in "Multiserver" mode in order for this to work? Or, am I just configuring something wrong? Is there another way to get CF and FDS to talk to each other without all this manual configuration?
Just install the 2 products, as 2 servers and start them up, they can find each other automatically. Granted you have more control if you use the multi-server mode (you can deploy them as 2 .war file applications in one server ). But as long as both servers are running you should be all set.
The only time you need to merge the servers, is if you want to serve both .mxml and .cfm files from your web server. However it's a much better idea to pre-compile the movies and just server the compiled .swf (like you would for any other flash movie).
