How ColdFusion and Flash Media Server interact through the FMS gateway
The FMS event gateway lets you modify data through the ColdFusion application or the Flash client, and reflect the
change in the Flash Media Server shared object. The FMS event gateway listens to the shared object, and notifies
ColdFusion when other clients modify shared objects. The FMS event gateway also lets ColdFusion modify shared
objects.
ColdFusion provides the following tools for developing FMS applications:
The JAR file that implements the Java API to communicate with Flash Media Server.
FCSj.jar
The class for the FMS event gateway type. You implement your FMS application by creating a
FMSGateway
ColdFusion application that uses an instance of the FMSGateway class to communicate with one or more Flash Media
Server.
Modifying data in the Flash client
The FMS event gateway listens to Flash Media Server shared objects, and notifies ColdFusion when a Flash client
modifies a shared object. The following steps occur when a Flash client modifies a Flash Media Server shared object:
1 A user modifies data in the Flash client.
Flash Media Server updates the appropriate shared object.
2
Flash Media Server notifies the FMS event gateway.
3
4 The FMS event gateway calls the appropriate methods in CFCs in your ColdFusion application. These CFCs
perform all actions required, including notifying the FMS Gateway Helper to update the shared object.
The FMS Gateway Helper sends a message to the FMS event gateway to update the shared object.
5
The FMS event gateway updates the shared object.
6
7 Flash Media Server notifies all the Flash clients that it modified the shared object. As a result, the Flash clients reflect
the change.
