Using the Data Management Event Gateway

Using the Data Management event gateway type provided with Adobe ColdFusion, you can have ColdFusion
applications notify Adobe Flex applications when data managed by a destination has changed. You configure the Data
Management event gateway and write an application that uses the event gateway.
Before using the Data Management event gateway, become familiar with ColdFusion event gateway principles and
programming techniques (see
About ColdFusion and Flex
ColdFusion includes the Data Management event gateway, which uses the ColdFusion Data Service Adapter to send
messages to LiveCycle Data Services ES. This means that ColdFusion applications can notify a Flex application about
changes in the data that the destination manages.
Note: To use the Data Management event gateway to send messages to a Flex application, the Flex application must be
running on LiveCycle Data Services ES.
How ColdFusion and Flex interact
You can send messages from a ColdFusion application to a Flex application through the Data Management event
gateway. This gateway type only lets you send messages from a ColdFusion application to a Flex application.
The following image shows the process in which a message is sent from the ColdFusion application to the Flex
application:

The ColdFusion application generates a message, which it sends to the ColdFusion server.
