Chapter 33. Introduction to WSE 2.0
IN BRIEF
The previous chapter provided an introduction to the basic concepts dealing with web services. You saw that a web service is essentially a method of transmitting messages over the Internet using an agreed-upon message format. Web Services Description Language (WSDL) defines the interface to the web service, whereas Simple Object Access Protocol (SOAP) defines the format of messages to be used in communicating between the service and the client.
This chapter will introduce you to additional web service standards, such as WS-Security, and other standards, such as DIME for attaching files to XML messages, and much more. Web Service Enhancements (WSE) 2.0 is a powerful set of tools and APIs that take the basic web service functionality to a whole new level. This chapter will show you just a few of the many different features available within WSE.
