Java Web Services gives the experienced Java developer a way into the Web Services world. It helps you to understand what's going on, what the technologies mean and how they relate, and shows Java developers how to put them to use to solve real problems. You'll learn what's real and what isn't; what the technologies are really supposed to do, and how they do it. Java Web Services shows you how to use SOAP to perform remote method calls and message passing; how to use WSDL to describe the interface to a web service or understand the interface of someone else's service; and how to use UDDI to advertise (publish) and look up services in each local or global registry. Java Web Services also discusses security issues, interoperability issues, integration with other Java enterprise technologies like EJB; the work being done on the JAXM and JAX-RPC packages, and integration with Microsoft's .NET services. The web services picture is still taking shape; there are many platforms and APIs to consider, and many conflicting claims from different marketing groups. And although web services are inherently language-independent, the fit between the fundamental principles on which Java and web services are based means that Java will almost certainly be the predominant language for web services development. If you're a Java developer and want to climb on the web services bandwagon, or if you only want to "kick the tires" and find out what web services has to offer, you will find this book indispensable.
