Standard event gateways
Macromedia provides several event gateways as part of ColdFusion MX. These event gateways support the following messaging protocols:
- SMS (Short Message Service) A system designed for exchanging short, often text, messages with wireless devices, such as mobile phones or pagers. For detailed information on using the SMS event gateway, see Using the SMS Event Gateway.
- XMPP (Extensible Messaging and Presence Protocol) An open, XML-based protocol for instant messaging. For detailed information on using the XMPP event gateway, see Using the Instant Messaging Event Gateways.
- IBM Lotus Instant Messaging (commonly referred to as Lotus Sametime) The IBM product for real-time collaboration. For detailed information on using the Lotus Sametime event gateway, see Using the Instant Messaging Event Gateways.
ColdFusion MX also provides an event gateway, the CFML asynchronous event gateway, that lets a CFML application invoke a CFC method asynchronously. This event gateway does not follow the model of providing a mechanism for exchanging messages with resources outside of ColdFusion MX. Instead, it provides a one-way path for invoking CFCs when an application does not require (indeed, cannot receive) a return value from the CFC. For detailed information on using the CFML asynchronous event gateway, see Using the CFML event gateway for asynchronous CFCs.
