This method first invokes
Service
's
Service create(QName ser-
viceName)
method to create a
Service
instance that provides a client view of a
web service. Incontrast to a
Service
instance created from a WSDL file, where the
qualified name of the service implementation class and other information is known to
the
Service
instance, a
Service
instance created byadispatch client doesn'tneed
tohaveknowledgeoftheservicewhencreated;theinformationwillbeprovidedtothis
instance shortly. As a result, a
QName
instance with an empty qualified name can be
passed to
create()
.
A
Dispatch<T>
instance must be bound to a specific port and endpoint before
use. As a result,
doGet()
next invokes
Service
's
void addPort(QName
portName, String bindingId, String endpointAddress)
method
tocreateanewportfortheservice.(PortscreatedwiththismethodcontainnoWSDL
port type information and can be used only for creating
Dispatch
instances.) The
QName
argumentpassedto
portName
cancontainanemptyqualifiedname.However,
an appropriate binding must be specified via a
String
-based binding identifier. This
example specifies
HTTPBinding.HTTP_BINDING
because we are communicating
