J2EE Web Services (Paperback)

"This is the best—and most complete—description of J2EE Web services that I've seen. If you're a Java developer, you need this book."
—David Chappell, Chappell & Associates

Web services are revolutionizing the way enterprises conduct business, as they allow disparate applications to communicate and exchange business data. Now, Java 2, Enterprise Edition (J2EE™) delivers a complete Web services platform. But how do you make sense of the sea of acronyms in this emerging area? Richard Monson-Haefel comes to the rescue with this essential guide for Java developers who need to understand J2EE APIs for Web services and the Web services standards.

J2EE™ Web Services is a comprehensive guide to developing and deploying Web services using J2EE technology. Concentrating on standards sanctioned by the Web Services Interoperability Organization (WS-I) for maximum interoperability, the author delves into Web-service standards and the J2EE 1.4 Web-service APIs and components with clear and engaging discussions.

Key topics covered include:

XML (eXtensible Markup Language) and XML Schema

SOAP (Simple Object Access Protocol)

WSDL (Web Services Description Language)

UDDI (Universal Description, Discovery, and Integration)

JAX-RPC (Java API for XML-based RPC)

SAAJ (SOAP with Attachments API for Java)

JAXR (Java API for XML Registries)

JAXP (Java API for XML Processing)

The appendices complement this wealth of information with coverage of XML regular expressions, Base 64 encoding, DTDs (document type definitions), SOAP Messages with Attachments (SwA), RCP/Encoded SOAP messaging, and references to other resources. In short, this accessible reference will give Java developers the tools they need to use J2EE technologies and APIs to integrate both enterprise applications and Web-based applications.
