Integration Server can use WML (Wireless Markup Language) output templates or HDML (Handheld Device Markup Language) output templates to return output to Internet-enabled wireless devices. You might want to return service output in WML and HDML if you allow the use of wireless devices to invoke services on Integration Server. For example, if you allow clients to submit purchase orders using a wireless device, you would want to be able to send their order confirmation to the wireless device.

For information about how Integration Server communicates with a wireless device, see webMethods Integration Server Administrator’s Guide.
