Java Web Services Development (3 days) print Download

course overview

This course begins by introducing essential Web service concepts, and describes how to create and consume simple SOAP-based Web services. The course also explains the important role of WSDL in describing Web service interfaces.

The course then digs 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 course also describes how to create and consume RESTful Web services, and explains how to access RESTful Web services by using JAX-RS.
