Since CXF provides integration with the Spring framework, we can leverage the dependency injection capability of Spring in our applications. So we will be creating two xml files. One for Spring CXF integration and another web.xml.

web.xml, as we know, is the web application configuration file that defines a servlet and its properties. The file defines CXFServlet, which acts as a front runner component that initiates the CXF environment.

web.xml also defines the listener class ContextLoaderListener, which is responsible for loading the server-side configuration file appContext.xml. So on web server startup, the HelloWorldRestServiceImpl RESTful service will be registered and available over the address.
