Hi Mike. You can use the CRXDE Lite editor to modify the services-config.xml file for a Data Services application deployed to the Experience Server.
When you are in CRXDE Lite, navigate to:
Open the services-config.xml, make your changes, and click the Save All button.
After that, when you create a new "Flex for ADEP Experience Services" project in Flash Builder, the channelset-config information will be copied from the services-config.xml file into a channelset-config.xml file that gets added to the dataservices directory of your Flex project and is also added to the mxmlc compiler options for your project.
