A Web Service is a distributed application or business logic process that is accessed using standard Internet protocols. Web Services combine the best aspects of component-based development and the WWW.
Like components, Web Services give "black-box" functionality that can be used and reused without regard to how the service is implemented.
The course provides an overview introducing the use of Java Web Services. The course introduces delegates to the latest strategic and practical issues in using Java APIs for developing Web Services
Available as a public or closed course at our London training centre, or can be tailored to your team's requirements and delivered onsite as a bespoke, customised training course.
