asyncprovider sample demonstrates JAX-WS RI specific endpoint to achieve
     server side asynchrony.
     
     * etc - configuration files
         * hello_literal.wsdl wsdl file
         * custom-client.xml client customization file
         * custom-server.xml server 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/AsyncClient.java - client application
         * server/AsyncHelloImpl.java - server implementation
     
     * wsimport ant task is run to compile etc/hello_literal.wsdl
         * generates
           SEI - Hello
           service class - Hello_Service
     
     * To run
         * set JAXWS_HOME to the JAX-WS installation directory
         * ant clean server - runs wsimport to compile hello_literal.wsdl and
           generate server side artifacts and does the deployment
         * ant clean client run - runs wsimport on the published wsdl by the deployed
           endpoint, compiles the generated artifacts and the client application
           then executes it.
