Problem in Authenticating using Axis2

[sudeep naayak]

Hi,

I'm working on calling some remote methods by using WSDL url.
The remote service is based on cordys technology.
In order to access the remote methods I have to authenticate at the web service client (Axis).

I am using netbeans 6.8

Now I got the Error as follow

javax.xml.ws.WebServiceException: Failed to access the WSDL at: www.example.com/service.wcp?service=.... It failed with: Server returned HTTP response code: 401 for URL: . . . .

Please somebody tell me how to authenticate in Axis2.

Any response is appriciated.Thanks in advance.
