userid, passwd info set in call object not getting to .NET servic e

["Chakraborty, Anirban" <ac...@rational.com>]

Hi,

I have a java webservice that acts as a client to a .net webservice.

following is the code snippet on the client side:
....
Service service = new Service();
Call _call = (Call) service.createCall();
_call.setUsername(userName);
_call.setPassword(passwd);
....

The http header in the wire looks like following:

POST /WebService1/Service1.asmx HTTP/1.0
Content-Type: text/xml; charset=utf-8
Accept: application/soap+xml, application/dime, multipart/related, text/*
User-Agent: Axis/1.0
Host: anirban
Cache-Control: no-cache
Pragma: no-cache
SOAPAction: "http://tempuri.org/DeleteProject"
Content-Length: 366
Authorization: Basic QUNXZWJTZXJ2aWNlOmFjd3M=

On the .net side, I see that the http request object contains headers upto
content-length and completely ignores the Authorization info. In the .net
debugger, I see that IsAuthenticated=false,
System.Web.Services.WebService.User.Name="", and
System.Web.Services.WebService.User.AuthenticationType="". 
Do I need to set something else in order to get non empty username and
passwd in IIS? 

I'm using axis 1.0 release.

Also, I see that the HTTP version set in the request is 1.0. Is there a way
to set it to 1.1 before sending the request to the server?

Thanks in advance.
