The ongoing Web services trend is ubiquitously featured already - many publications on Web services exist. The first wave of enterprise-scale applications and projects exploiting the benefits of the technology is on its way. However, there is still a lack of experience in the field - technical decision makers are struggling about when to apply which elements of the technology, and how to do so. This is a variation of the well-known chicken and egg" problem: no project without an architectural decision, no architectural decision without experience, no experience without a project. This book provides technical guidance and helps the reader to cut the Gordian knot." Key Topics - Seven - sometimes controversial - Perspectives on Web services, covering the entire project lifecycle from opportunity identification to design, development, and deployment - Introduction to Web services architectures as defined by the World Wide Web Consortium (W3C), and their Java 2 Enterprise Edition (J2EE) instantiations - Understanding the Web services building blocks SOAP, WSDL, and UDDI - Business scenarios and functional/non-functional requirements for Web services solutions - Patterns for Web services projects and related architectural decisions - Sample implementation platform: IBM WebSphere Studio integrated development environment and IBM WebSphere Application Server Version 5 - Full-scope implementation of an end-to-end case study, including hands-on instructions for development and deployment - Apache SOAP 2.3 as well as JAX-RPC programming through JSR 109 and Apache Axis - Interoperability between Microsoft .NET C# and Apache SOAP - Runtime topologies for Web services solutions, deployment to WebSpheContains everything that a project team needs to know about the development and deployment of Web services with the IBM WebSphere product family. Included will be examples for all development artifacts in a format that can be reused in the reader's project. It combines the authors' own practical experiences with consolidated information on the latest product capabilities in a unique approach that allows the book to be easily accessible to a broad spectrum of readers. Finding a balance between a euphoric/optimistic and down-to earth/realistic view on the subject, this book will be an essential part of every Web service developer's bookshelf.

Rezensionen
"Web Services have emerged as a powerful tool for building complex but adaptive and agile enterprise systems in heterogeneous environments, enabling effective inter- and intra-enterprise integration. Perspective on Web Services: Applying SOAP, WSDL, and UDDI to Real-World Projects by Olaf Zimmermann, Mark R. Tomlinson, and Stefan Peuser contains erverything you need to know about developing and deploying Web services-oriented enterprise applications. Whatever your role in a Web Services application project - for example, software architect, developer, project manager, or systems administrator - you will find useful information in this book. (...) The authors combine their practical experience in Web service-oriented enterprise applications with reviews and a hands-on examination of the latest Web service specifications and technologies and IBM product capabilities." -- Dragan Stojanovic on dsonline.computer.org
