Failed to create XMLHttpRequest object

neethupk

I am trying to test webservice using Sahi. I cannot create a XMLHTTPRequest object, hence the code fails. How to create XMLHTTPrequest object in Sahi?
Is it needed to import any classes for this? How it can be done?

My code is like this.

var $url= "http://10.1.5.241/emswebservice/GISWebInterface.asmx";
var $authHeader = "application/x-www-form-urlencoded";
var request = new new XMLHttpRequest();

var XMLdata="<?xml version='1.0' encoding='utf-8'?>"+
"<soap12:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap12='http://www.w3.org/2003/05/soap-envelope'>"+
"<soap12:Body>"+
"<CheckUserCredentials xmlns='http://tempuri.org/'>"+
"<username>username</username>"+
"<password>passwd</password>"+
"</CheckUserCredentials>"+
"</soap12:Body>"+
"</soap12:Envelope>";

request.open("POST", url, false);
request.setRequestHeader("Content-Type", "text/xml");
request.setRequestHeader("ATH", authHeader);
request.send(XMLdata);

var response = {};

response.statusText=request.statusText;
response.status=request.status;
response.responseText=request.responseText;
