Webservice 401 problem

Question

Hello all
I tried to consume a web service using webdynpro model. When I run the web service I get the following error:
java.rmi.RemoteException: Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException : <b>Invalid Response Code: (401) Unauthorized</b>. The requested URL was:"http://<xxx>/<yyy>/xxxService.svc"
My colleague used this web service successfully by .NET and they told me that I should explicitly set UseDefaultCredentials to true.
They are using the following codes for using the webservise:
string url = " http://<xxx>/<yyy>/xxxService.svc ";
xxxService xxxWcfService = new xxxService (url);                                                        
<b>xxxWcfService.UseDefaultCredentials = true;</b>
How and where should I set UseDefaultCredentials to true in my webdynpro project?
I am using the following code for instancing and binding the webservise in wdDoInit() function of component controller:
Request_xxx req = new Request_xxx
wdContext.nodeRequest_xxx().bind(req);
and following codes for execute the web service:
wdContext.currentRequestElement ().modelObject().execute();
Thanks in advance

Hi Yoel,
I think that 'UseDefaultCredentials' in .NET passes to current user data to the Web Service.
So, your credentials are sent to the server.
Assuming your colleague is running the Web Service from <b>his</b> computer then <b>his</b> Credentials are sent and authenticated.
Try to run the .NET appilcation from your computer (under your account).
Also, ask your colleague for username & password and pass them to the WebService like this:
xxxWcfService._setUser(user)
xxxWcfService._setPassword(password)
