Is this a JAX-RPC limitation or have I missed something obvious?

Hi,

I am trying to use Servlet deployment descriptor declarations to apply
access control to an Axis services. This works fine for accessing the WSDL
or service through a browser (Imean, the browser throws up an
username/password dialog box and proceeds to dowload the WSDL). However,
when I try to access the service through a DII client (source code given
below ), I get an exception. I suspected that the code is trying to access
the WSDL from Axis and is failing there because Axis servlet is asking for
authentication. SO I stored the WSDL in file and specified wsdlAddr as
"file:temp.wsdl", a URL pointing to a local file. This worked fine.

Now, JAX-RPC allows me to set the USERNAME_PROPERTY and USERNAME_PASSWORD in
a Call object but not in ServiceFactory which retrieves the WSDL document.
Is this a JAX-RPC limitation or have I missed something obvious?
