I created a video on how to link a Flex project to LCDS/BlazeDS configuration files. You view the video at the URL below. The video shows how to map your services-config.xml to a Flex project, so that your destinations are identified in your Flex application.

Hope this is useful. Please let me know if you like us to create similar short videos for any topics.
Enjoy 🙂
