Denise Hatzidakis – Perficient, Inc.

How many acronyms does it take to make a technology? In this session we will examine the many specifications that make up "Web Services" technology and where each technology is positioned in the Web Services solution. We will look at each of the key Web Services technologies and their use in designing/delivering a Web Services based solution.

As the J2EE arena continues to grow and evolve, Web Services is a key part of that growth. JAX/RPC and JSR 109 are two of the latest specifications to expand J2EE support in the Web Services arena. Together they define the Web Services Programming Model. JSR 109 effectively 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 (a.k.a. JSR 101) contributes to the programming model by defining a type mapping system, a major step towards interoperable Web Services, and a serialization framework to support the type mapping.

In this session we will examine:

The Client-side programming model? How J2EE applications can access Web services as if they were "traditional" remote objects.

Server-side programming model? How Web services can be implemented as servlets and stateless session EJBs and their lifecycle.

Web service deployment and deployment descriptors? How Web services might be deployed in a compliant application server.
