/**
 * Service objects provide the client view of a Web service.
 *
 * 
Service acts as a factory of the following:
 * 
    
 * 
  • Proxies for a target service endpoint.
 * 
  • Instances of javax.xml.ws.Dispatch for
 * dynamic message-oriented invocation of a remote
 * operation.
 * 
    • 
 *
 * 
    The ports available on a service can be enumerated using the
 * getPorts method. Alternatively, you can pass a
 * service endpoint interface to the unary getPort method
 * and let the runtime select a compatible port.
 *
 * 
    Handler chains for all the objects created by a Service
 * can be set by means of the provided HandlerRegistry.
 *
 * 
    An Executor may be set on the service in order
 * to gain better control over the threads used to dispatch asynchronous
 * callbacks. For instance, thread pooling with certain parameters
 * can be enabled by creating a ThreadPoolExecutor and
 * registering it with the service.
