WAP (Wireless Application Protocol) is currently the standard for wireless information and telephony services on digital mobile phones and other wireless devices. It is an open, global wireless protocol specification based on existing Internet standards - such as XML and Internet Protocol (IP) - for all wireless networks. The PMOffice™ Internet architecture natively supports WAP. The User Interface Generator and Presentation Relay Servlet are key pieces of the architecture that leverage WAP technologies such as WML and WMLScript.

The PMOffice™ Internet architecture leverages Web servers to perform several functions, including executing Java Servlets to serve data to HTTP client and using Java Servlets in the integration architecture to pass XML messages between systems.

The PMOffice™ Internet architecture uses XML in several areas to deliver powerful integration capabilities. Application Messaging publishes messages as XML documents, which provides a highly flexible and extensible platform for integration.
