Java Web Services gives the experienced Java developer a view into the XML-based Web services world. The book examines key Web services standards, such as Simple Object Access Protocol (SOAP), Web Service Description Language (WSDL), and Universal Description, Discovery and Integration (UDDI), and the roles they play in providing a foundation for industry-accepted interoperability among applications and services in a Service Oriented Architecture (SOA). Yet standards by themselves don't solve problems without having real implementations to support them. Java Web Services takes a broad look at a number of the emerging Java-based approaches for working with Web services.

The chapter now available for preview, "SOAP - Cornerstone of Interoperability," takes a no-nonsense look at one of the key standards defining the move to Web services.
