OK. By rereading the spec, I get some some answers to my question.
The spec says the following under the section of 4.3.10 Service Interface.
"The method getPort(class) returns either an instance of generated stub
implementation class or a dynamic proxy. ... In the implementation of
this method, the JAX-RPC runtime system takes the responsibility of
selecting a protocol binding (and a port) and configure the stub accordingly.
The returned stub instance should not be reconfigured by the client."
So when you get a stub object using getPort() method, you are not
supposed to change the parameters.
The spec also says that in addition to getPort() method, the service
instance also supports get<Name_of_wsdl:port>() method which
also returns a stub object. JAX-RPC runtime system can optionally
support extra get<Name_of_wsdl:port>() methods in which
client can pass properties such as username and parameter. (I
am kind of curious why the spec does not define a set of standard
get<Name_of_wsd:port>() methods so that portability of code
can be guranteed in this case.)
So I guess the better sample code for the FCS release would be
to use get<Name_of_wsdl:port>() method in which target
endpoint address can be passed as a parameter. (This might
not be portable, however.) Comments?
