[jcifs] Propagation of windows credentials from Java client through to web service

[mileyd]

Hi 

I am running a jcifs.http.NtlmHttpFilter on tomcat. This filters requests prior 
to running my web services for which I use axis. 

My problem is that I would like to propagate the XP credentials users have 
already used to login to windows rather than popping up a login dialog and 
asking them to provide them again so they can log in to my application.

Using axis I need to provide the user and credentials either within the URL of 
the endpoint or using a credentials object. 

Something like:-
 
           String endpoint =
           "http://DOMAIN\\user:password@hostname:8080/NTLMAuthentication/axis/h
elloworld";
 
           Service  service = new Service();
           Call call    = (Call) service.createCall();
 
           call.setTargetEndpointAddress( new java.net.URL(endpoint) );
           call.setOperationName(new QName("sayHello") );
 
           String ret = (String) call.invoke( new Object[] { "Joe!" } );
 
           System.out.println("Sent 'Hello!', got '" + ret + "'");

Problem is I don't know how to get the user's current credentials using Java. I 
know the JDK uses native windows code in the URLConnection class somewhere to 
do the same thing but I cannot find how they do it. I know this is not specific 
to JCIFS, but I think this forum is the one best placed to understand my 
problem. Any ideas how to get at the cached windows credentials? Or am I going 
about this in totally the wrong way?

Thanks
