This book, written by two HP web services experts, is the authoritative guide to the UDDI registry technology in both Sun's J2EE and Microsoft's .NET environments. Registries are a cornerstone of web services. This book examines registries in detail, discussing the value proposition, providing hands-on examples for registering and discovering web services within XML-based registries, and including a survey of the registry competitive landscape. It covers all aspects of the service life cycle and walks readers through deploying a private UDDI registry. The book focuses on UDDI and to a much lesser extent, ebXML, and refers to supporting web services technologies where appropriate. UDDI (Universal Description, Discovery, and Integration) is an XML - based registry for businesses worldwide to list themselves on the Internet. Its ultimate goal is to streamline online transactions by enabling companies to find one another on the Web and make their systems interoperable for e-commerce. UDDI is often compared to a telephone book's white, yellow, and green pages.

This book introduces the main ideas and concepts behind core and extended Web services' technologies and provides developers with a primer for each of the major technologies that have emerged in this space.

CodeNotes provides the most succinct, accurate, and speedy way for a developer to ramp up on a new technology or language. Unlike other programming books, CodeNotes drills down to the core aspects of a technology, focusing on the key elements needed in order to understand it quickly and implement it immediately. It is a unique resource for developers, filling the gap between comprehensive manuals and pocket references. CodeNotes for Web Services in Java and .NET examines the core specifications and technologies required for building SOAP-based web services in both Java and .NET. Not only will you find descriptions of SOAP, WSDL, and UDDI; you will also see how to use each of these specifications with Java and .NET. In addition, you will find specific sections on cross-language and cross-platform compatibility between web services. This edition of CodeNotes includes: • A global overview of this technology and explanation of what problems it can be used to solve • Real-world examples • “How and Why” sections that provide hints, tricks, workarounds, and tips on what should be taken advantage of or avoided • Instructions and classroom-style tutorials throughout from expert trainers and software developers

"Addresses the evolution of database management, technologies and applications along with the progress and endeavors of new research areas."--P. xiii.

In this volume, Rudi Studer and his team deliver a self-contained compendium about the exciting field of Semantic Web services, starting with the basic standards and technologies and also including advanced applications in eGovernment and eHealth. The contributions provide both the theoretical background and the practical knowledge necessary to understand the essential ideas and to design new cutting-edge applications.

-- All the text of all three official W3C standards, conveniently formatted and thoroughly indexed. -- Includes expert commentary by Aaron Walsh, chairman of the Web3D Consortium's Universal Media Technical Group. UDDI, SOAP and WSDL are the three key specifications that will drive the Web Services revolution. Now, there's an authoritative one-stop technical specification reference for every developer who wants to use them: Web Services Specification Reference Book: UDDI, SOAP and WSDL presents the official text of all three standards, with expert commentary by a leading expert. The perfect companion to any other book on UDDI, SOAP, and WSDL, this book is the definitive standards reference -- always right at hand, with no time-consuming Internet downloads required! The book begins with an up-to-the-minute preface introducing UDDI, SOAP, and WDSL: their goals, elements, and current status. Learn how Universal Description, Discovery and Integration (UDDI) creates a platform-independent, open framework for describing services, discovering businesses, and integrating business services using the Internet. Understand Simple Object Access Protocol (SOAP), the XML/HTTP-based lightweight protocol for accessing services, objects and servers, enabling the creation of rich and automated Web services based on a shared and open Web infrastructure. Finally, understand the features and elements of the Web Services Description Language (WSDL), the XML-formatted language designed to describe the capabilities of any Web Service.

Like many other incipient technologies, Web services are still surrounded by a substantial level of noise. This noise results from the always dangerous combination of wishful thinking on the part of research and industry and of a lack of clear understanding of how Web services came to be. On the one hand, multiple contradictory interpretations are created by the many attempts to realign existing technology and strategies with Web services. On the other hand, the emphasis on what could be done with Web services in the future often makes us lose track of what can be really done with Web services today and in the short term. These factors make it extremely difficult to get a coherent picture of what Web services are, what they contribute, and where they will be applied. Alonso and his co-authors deliberately take a step back. Based on their academic and industrial experience with middleware and enterprise application integration systems, they describe the fundamental concepts behind the notion of Web services and present them as the natural evolution of conventional middleware, necessary to meet the challenges of the Web and of B2B application integration. Rather than providing a reference guide or a "how to write your first Web service" kind of book, they discuss the main objectives of Web services, the challenges that must be faced to achieve them, and the opportunities that this novel technology provides. Established, as well as recently proposed, standards and techniques (e.g., WSDL, UDDI, SOAP, WS-Coordination, WS-Transactions, and BPEL), are then examined in the context of this discussion in order to emphasize their scope, benefits, and shortcomings. Thus, the book is ideally suited both for professionals considering the development of application integration solutions and for research and students interesting in understanding and contributing to the evolution of enterprise application technologies.
