About Flex and ColdFusion

ColdFusion includes the Flex Messaging event gateway, which uses the ColdFusion Event
Gateway Adapter to send messages to and receive messages from Adobe Flex Data Services.
This means that ColdFusion applications and Flex applications can publish to and consume
events from the same event queue.
To use the Flex Messaging event gateway to interact with a Flex application, the Flex
application must be running on Flex Data Services.

Messaging event gateway. Conversely, you can send messages from a Flex application to a
ColdFusion application.
Either the ColdFusion application or the Flex application can initiate sending a message. The
