Web Services Building Blocks: SOAP

The Simple Object Access Protocol (SOAP) is an XML-based messaging and remote procedure call (RPC) specification that enables the exchange of information among dis-tributed systems.

The Simple Object Access Protocol (SOAP) is an XML-based messaging and remote procedure call (RPC) specification that enables the exchange of information among dis-tributed systems. Initially proposed by Microsoft, SOAP has established itself as the de facto standard for an open, extensible, XML-based wire protocol.

SOAP has achieved its level of widespread acceptance for several reasons:

It is an open specification, available for anyone to use.

It is simple to write and is “human-readable.”

It is extensible, taking advantage of the power of XML to enable loose coupling between remote systems.

It is a flexible protocol that is useful both in request/response and message pass-ing/queuing architectures.

Even though SOAP has wide application in the distributed computing environment, prob-ably its most significant role is as a building block for the Web Services model, intro-duced in Chapter 14, “Architecting Web Services.”

In this chapter, you will learn
