XFire Authentication Failure

[dhaval nagar]

I am consuming a web service running inside SAP Xi.
SAP team has given a basic SOAP authentication, when i am testing the web service through XmlSpy or SoapUi it is running perfectly.

But it is giving authentication failure (401 HTTP error) while calling from my Java program using XFire framework.

I tried to authentication through Client class and OutHandler but the error is same.

Any help is appreciated.
