Overview
Learn how to develop REST-style and SOAP-based web services and clients with this quick and thorough introduction. This course delivers a clear, pragmatic approach to web services by providing an architectural overview, complete working code examples, and short yet precise instructions for compiling, deploying, and executing them. You’ll learn how to write services from scratch and integrate existing services into your Java applications.
With greater emphasis on REST-style services, this course covers HttpServlet, Restlet, and JAX-RS APIs; jQuery clients against REST-style services; and JAX-WS for SOAP-based services. Code samples include an Apache Ant script that compiles, packages, and deploys web services.
