This module demonstrates how to develop a web services application using JAX-WS. JAX-WS provides APIs for developing SOAP-based web services. JAX-WS uses the SOAP standard and HTTP. This allows client programs to make XML-based calls over the Internet. JAX-WS also supports WSDL, which allows you to import and export WSDL documents.

The stages involved in developing web services include configuring the environment, developing the web service, exposing the web service, and consuming the web service.
