    Servlet + Ajax woes. XML doc returned from servlet not working for ajax code.

    I have a servlet that reads data out of a text file and sends that data as an xml page. The servlet is hosted on http://localhost:8080/Checkers/CheckersServlet. I made it in Eclipse IDE for Java EE and host it on a Tomcat server. I can open that url in firefox and it loads the xml fine. How do I call on the servlet from the ajax code. Do I write something like


    Code:
    var req = new XMLHttpRequest();
    		req.onreadystatechange = function()
    		{	
    			if(req.readyState == 4)
    			{
    				displayResult(req);
    				
    			}
    		}
    		var url = "http://localhost:8080/Checkers/CheckersServlet";	
    		req.open("GET",url,true);
    		req.send(null);
    where displayResult(req) is a custom function that does what I want with the xml received from the servlet? This is the code I am trying to use but it isn't working, and I've confirmed the reason is that I am not getting any xml from the servlet.
