With SOA’s rise to prominence in the enterprise scene, most new applications being developed today need to deal with web service-based integrations. Whether your application is a service provider or a consumer, a solid strategy for handling web services is an integral part of its architecture. Fortunately, there are a number of open source frameworks available that can free developers from much of the complexity of implementing SOAP-based web services. In this session, I will introduce several leading frameworks including Apache Axis2, Apache CXF, Sun/Metro Web Services and Spring Web Services. I will compare and contrast each framework and examine their built-in support for Spring. Then we’ll build a real-world example, exposing SOAP web services from an existing Spring application.
