Chapter 31. Event Gateways > What Is an Event Gateway?

What Is an Event Gateway?

ColdFusion MX 7 gateways are Java classes that implement an application programming interface (API) provided with the CFMX7 application server. Figure 31.1 shows a high-level diagram of the event gateway communications. Event gateways communicate with the ColdFusion event gateway services through CFEvent objects, which we will define later in this chapter. The event gateway service system puts CFEvent objects, if necessary, in a queue and then passes them to the ColdFusion run-time engine for processing as input to ColdFusion Components (Listener CFCs). The Listener CFC might return output to the event gateway services subsystem and then back to the event gateway.
