While issues relating to integration and interoperability are referenced and discussed throughout this book, service-oriented integration as a specific topic is not covered. This is to prevent overlap with Service-Oriented Architecture: A Field Guide to Integrating XML and Web Services, this book's companion guide. The Field Guide is dedicated to matters of integration and explores numerous service-oriented integration architectures, strategies, and best practices.
Also though this book will be useful to developers who want to understand how to build services for SOA and how different technology platforms support the SOA model, this is not a book that explains how to program Web services using any particular programming language. The step-by-step instructions provided focus on building and orchestrating service endpointsnot the underlying component logic. We therefore supply tutorials and/or code examples for the following open Web services languages: WSDL, SOAP, XML Schema, WS-BPEL, WS-Coordination, WS-Policy, WS-MetadataExchange, WS-Security, WS-Addressing, and WS-ReliableMessaging.
A knowledge of XML is recommended prior to reading this book. Suggested reading materials are listed at www.serviceoriented.ws, and a collection of introductory papers can be found at www.xmltechnologyexpert.com.
