About the Book

E-speak is an open, Java and XML-based software platform designed by HP to simplify the creation and delivery of e-services and web services (collectively called Internet-services) that make the web work for you. This book is a comprehensive guide to e-speak technology. Written by two HP e-speak experts, it covers every aspect of Java-based service development and deployment, while illuminating broader issues associated with Internet-service based economies. The authors show how e-speak enables Internet-service providers to find and interact with each other automatically -- across platforms, and even behind firewalls, using a robust, end-to-end security infrastructure. They compare HP's e-speak initiative with UDDI and .NET; offer insight into Web services, e-services, and the differences between them; and preview e-speak's future as a standards-based, highly interoperable platform for Internet service delivery. Next, they cover e-speak development, deployment, and operation.
