/**
* Simple exporter for JAX-WS services, autodetecting annotated service beans
* (through the JAX-WS {@link javax.jws.WebService} annotation) and exporting
* them through the HTTP server included in Sun's JDK 1.6. The full address
* for each service will consist of the server's base address with the
* service name appended (e.g. "http://localhost:8080/OrderService").
*
* <p>Note that this exporter will only work on Sun's JDK 1.6 or higher, as well
* as on JDKs that ship Sun's entire class library as included in the Sun JDK.
* For a portable JAX-WS exporter, have a look at {@link SimpleJaxWsServiceExporter}.
