dual_binding sample demonstrates the SOAP/HTTP and XML/HTTP for the same
     service class
     
     * The service implementation class has one method:
         * addNumbers() that takes two integers and returns an integer
     * etc - configuration files
         * custom-client.xml client customization file
         * build.properties, deploy-targets.xml ant script to deploy the endpoint
           war file
         * sun-jaxws.xml deployment descriptor for web container
     * src source files
         * client/AddNumbersClient.java - client application
         * server/AddNumberImpl.java - server implementation
     
     * annotationProcessing ant task is run to compile AddNumbersImpl and create server
       objects used during deployment and runtime.
     
     * To run in servlet container
         * set JAXWS_HOME to the JAX-WS installation directory
         * ant clean server - runs annotation processing to generate server side artifacts and
           does the deployment
         * ant clean client - runs wsimport on the published wsdl by the deplyed
           endpoint, compiles the generated artifacts
           then executes it.
         * ant run - runs the client application
           ant run -Dlog=true shows what is going on the wire
