Java Web Services Devlopment
This course is suitable for anyone new to Java
Course Content 3 Days

This course describes how to create and consume Java Web services. The course is based on the latest platform for Java Web service development ("Metro").

The first day of the course introduces essential Web service concepts, and describes how to create and consume simple Web services. You will also learn about the important role of WSDL in describing Web service interfaces.

The second and third days of the course dig deeper into Web service standards, techniques, and APIs. You will learn how to handle Web service faults; maximize integration options; use headers to provide Web service metadata; customize Java-to-object serialization formats; and invoke Web services programmatically by using JAX-WS, the latest Java API for Web services. The course also describes how to create and consume RESTful Web services, and explains how to access RESTful Web services by using JAX-RS.

The course also includes several optional appendices that provide supplementary information, to give students good insight into additional techniques.
