About the Book

Web services is the convergence of a suite of technologies into a cohesive whole. It unifies approaches that we as an industry have been doing in a standalone manner for many years. Java is a powerful technology that has contributed to the successful development of many large, mission-critical enterprise applications yet on its own is relatively powerless. When an enterprise combines Java with other industry principles such as XML, UML, object orientation, design patterns, and a good software development process, it can create meaningful services with strong value propositions: the key to Web services and this book. The authors recommend that the chapters in this book, or at least in each part, be read in order, as each chapter builds on the previous one.

The authors of this book have intentionally avoided presentating any formal software development process for Web services. The only processes mentioned in this regard are those that are time-tested and proven to lead the reader to success. UML notation is expansive. This book limits its examples and usage of UML to use cases, class diagrams and sequence diagrams, as these are the most useful in the development lifecycle. It is suggested that if you are unfamiliar with this topic, you are recommended to immediately purchase Core J2EE Patterns and Design Patterns.

About the Chapters

In Chapter 2, " Service Oriented Architecture, " this chapter shows how service-oriented architectures allow for business logic to be invoked across a network and can be discovered and used dynamically. A service is a behavior that is provided by a component for use by any other component based service using only the interface contract. It stresses interoperability and may be dynamically discovered and used.

In chapter 10, " JAX-RPC, " introduces and shows how the Java API for XML-Based Remote Procedure Calls enabled Java applications to develop SOAP-based interoperable and portable Web services.

In chapter 14, " Transaction Management, " introduces and shows how to conduct electronic commerce using Web services, a service will need to support ACID like transaction models.
