ColdFusion MX 7 has some exciting new functionality but the most important and revolutionary of these new features, hands down, is the event gateway. Event gateways are to application server environments what the CFQUERY tag was to database interaction. As you will see, the event gateway technology transforms ColdFusion MX 7 (CFMX7) from just another Web application server to an enterprise services platform, allowing CFMX7 applications to work with just about any other application and/or platform over any well-defined protocol including SMS, RMI, MQ, JSM, AMS, TCP, and UDP. If you have ever worked with message-oriented middleware, much of the paradigm behind event gateways will be obvious to you. On the other hand, if you've not, the ColdFusion event gateway operates like MOM.
