I am calling a servlet from JavaScript with request parameters but the servlet is not getting called.

<script>
$('td').click(function(){
var colIndex = $(this).parent().children().index($(this));
var rowIndex = $(this).parent().parent().children().index($(this).parent());
alert('Row: ' + rowIndex + ', Column: ' + colIndex);
var xhr = new XMLHttpRequest();
xhr.open('GET', 'http://localhost:8080/TestFinalWebApp/MyServlet?rowIndex=' + rowIndex + "&colIndex=" + colIndex, true);
xhr.send(null);
});
</script>
</body>

This is the deployment descriptor:
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">

</servlet>
<servlet-mapping>
<servlet-name>GetParameters</servlet-name>
<url-pattern>/MyServlet</url-pattern>
</servlet-mapping>
</web-app>
EDIT:
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String rowIndex = request.getParameter("rowIndex");
String colIndex = request.getParameter("colIndex");
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.print("rowIndex:" + rowIndex + " colIndex:" + colIndex);
}
Can you please tell me why the servlet is not getting called?
