Summary:

This IBM Redbook describes the concepts of Web services from various perspectives. It presents the major building blocks on which Web services rely. Here, well-defined standards and new concepts are presented and discussed. While these concepts are described as vendor independent, this book also presents the IBM view and illustrates with suitable demonstration applications how Web services can be implemented using the IBM product portfolio, especially IBM WebSphere Application Server Version 6.0 and IBM Rational Application Developer for WebSphere Software Version 6.0.
