Unable to access a Lotus Domino 8 Web Service

Hi All

I have deployed a simple Web Service in Lotus Domino 8 Server.

When I try to access the web service through a Web Service Client I get the following Error

faultcode xmlns:ns1=“WebServices - Axis”>ns1:HTTP

(401)Unauthorized

<string>return code:  401

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>Error</title></head>

<body text="#000000">

<h1>Error 401</h1>You are not authorized to perform this operation</body>

</html>

</ns1:Fault>

Inspite of giving the correct credentials it does not work.

But I can see the WSDL in IE when the same credentials are given

The problem comes only when I try to invoke the web service through a Web Service Client.

My requirement is that I should be able to invoke the web service without giving any credentials.Is that possible?

Please help me in this regard.
