Résumé

Building Web Services with SOAP, XML, and UDDI assumes proficiency with Java and with distributed computing tools. Throughout the book, examples will be presented using Java and the Apache SOAP platform, although a set of sidebars will address .NET development, which Microsoft developers will use to deploy Web services. The book uses progressive disclosure to present an increasingly complex project as it moves through its development cycle. The final section of the book presents linking the completed project with other systems built in J2EE and .NET.
