Perspectives on Web Services

Applying SOAP, WSDL and UDDI to Real-World Projects

This book is designed as a full and rich source book for architects, developers and project managers of Web services projects.

The book is written by experienced practitioners. The text is accompanied by a realistic case study which leads the reader through a complete project lifecycle. J2EE and the IBM WebSphere product family serves as the sample implementation platform for the introduced concepts.
