TempVerterClient
first creates a
java.net.URL
instance that identifies the
web service's WSDL file. It then creates a
javax.xml.namespace.QName
in-
stance that identifies the endpoint's qualified service name (see
Figure 11-6
). These
instances are passed to the
javax.xml.ws.Service
class's
Service cre-
ate(URL wsdlDocumentLocation, QName serviceName)

return a
Service
instance that provides a client view of a web service.
Service
's
T getPort(QName portName, Class<T> serviceEnd-
pointInterface)
method is then called on the
Service
instance to return a
proxy for communicating with the web service via its endpoint. The qualified name
