Evolving from a basic XML messaging framework to a full-fledged backbone for distributed applications, web services technology has the promise to provide a standard, interoperable way to integrate applications on heterogeneous platforms. With the vast amount of data and crucial business logic stored in relational databases, exposing those resources through web service is the first major step towards SOA adoption. EclipseLink, the leading persistence runtime framework, supports a powerful and yet easy way to create database web services. Built on top of its proven ORM(Object-to-Relational) and OXM (Object-XML) mapping capabilities, EclipseLink DBWS(Database Web Service) provides a declarative, metadata-driven development model, which is non-invasive from the database administration standpoint. It allows creates web services from SQL statements in a database-agnostic fashion.

This session discusses the unique architecture of EclipseLink DBWS, examines application configuration and packaging model, and demonstrates its core functionality. We will also cover how EclipseLink DBWS addresses web service interoperability and support for WS-* standards, more specifically WS-AtomicTransaction. Finally, we will compare EclipseLink DBWS with other alternative ways to integrate database into SOA environments.

At the end of the session, the audience will understand what EclipseLink DBWS is, and how to get started with developing database web services using EclipseLink. This presentation is aimed towards SOA, JEE architects and application developers who need to develop web services out of database artifacts in a productive, and flexible way.
