Creating a New Flex Project Using ColdFusion 8 with LiveCycle Data Services
I was a bit confused when I first tried to create a Flex project that used ColdFusion's built-in version of LiveCycle Data Services. In the old days, setting up an FDS project meant creating a new folder under an existing context, such as /flex, which was located under /jrun4/servers/default/flex. I started looking for the "root" of the LCDS server within my ColdFusion installation and assumed that there was some secret undocumented location.
After some playing, I found that, amazingly, I could just use ColdFusion's web root (wwwroot) when setting up the Flex project!
Here's the step-by-step (if you promise not to ask what OS I'm running Flex Builder on;)
Create a Flex Data Services Project:
Use your CF installation's web root as the root folder. Make sure you validate the location before moving on. Your folder name might be different depending on what OS you're using:
Add your project information:
An mxml file running off a ColdFusion installation (sweet):
Another interesting side note: the LCDS config files are located under {coldfusion8}/wwwroot/WEB-INF/flex. You'll also see the /user_classes and /libs folders located there.

useful infomation is skipped. Thank you.
