Now that the application is running, let's walk through the code.

• The web application is wired using the web.xml
• The web service functionality is provided through the Apache CXF - CXFServlet, this servlet takes care of handling the web service request and sending the calls to the corresponding end points defined using annotations and configured using spring
• Rest of the application code is wired through Spring 2.5.6 using application-context.xml
