Summary

SOAP (Simple Object Access Protocol) was co-developed by IBM and Microsoft and is an XML-based messaging protocol for creating distributed Web applications. In plain English: it solves a basic business problem, which is creating Web applications that have to talk with servers that are running on different platforms (Windows, Unix, Linux etc.). SOAP offers an XML-based method to pass business data for e-commerce applications through corporate firewalls. The significance of peer to peer services and .NET in the enterprise has been a focus of O'Reilly's publishing program. Together with the XML-RPC and other peer to peer series these titles show programmers and system designers the way forward in this exciting new environment. As part of the Programming Web Services series it provides solid information in a familiar and easy to absorb form.

Author Biography

James Snell is a member of IBM's emerging software technologies team where his work is dedicated to the evolving Web services architecture.

Doug Tidwell is a senior programmer at IBM. He has more than a sixth of a century of programming experience, and has been working with markup languages for more than a decade. He was a speaker at the first XML conference in 1997, and has taught XML classes around the world. His job as a Cyber Evangelist is to look busy and to help people use new technologies to solve problems. Using a pair of zircon-encrusted tweezers, he holds a master's degree in computer science from Vanderbilt University and a bachelor's degree in English from the University of Georgia. He lives in Raleigh, North Carolina, with his wife, cooking teacher Sheri Castle (see her web site at http://www.sheri-inc.com) and their daughter Lily.
