Web Services... Where Do You Start – SOAP, WSDL and UDDI

So you want to start building Web Services.... What are SOAP, WSDL and UDDI? Where do you start? In this session we will look at the core Web Services technologies of SOAP, WSDL and UDDI and understand how these technologies come together to provide a foundation for building Web Services. We will discuss the basics of the technologies and explore examples to solidify the concepts key to SOAP, WSDL and UDDI. We will also look at how to build a Web Service using these technologies and the classic, top-down and bottom-up approaches.

Web Services Integration – It’s All About Standards

J2EE 1.4, the current J2EE specification, now includes several Web Services standards. Key to the standards is the Web Services programming model defined by JAX/RPC and JSR 109. JSR 109 defines how a J2EE application server could be expanded to provide native support for deploying, managing, and accessing Web services in a standard fashion. JAX/RPC contributes to the programming model by defining a type mapping system, a major step toward interoperable Web Services, and a serialization framework to support the type mapping.

In this session we will examine the key aspects of these standards and look at example implementations based on these standards. Building Web services based on these standards is the foundation for building interoperable Web Services.
