Getting null while doing jquery ajax call to read data from database

Getting null while doing jquery ajax call to read data from database

Hi All,
I am calling jquery-ajax function to read data from database using servlets and display in html page on page load. But in html age, its coming as null.
Code is as below:

<div id="anuj1"></div>


$(document).ready(
        $.callme = function () {
            $.ajax({//create an ajax request to display.php
                type: "POST",
                url: "ReadDataBaseValue",
                dataType: "html", //expect html to be returned                
                success: function (response) {
                  $("#anuj1").html(response);
                    
                }

            });
        });

In servlet(servlet url is- "ReadDataBaseValue")

response.getWriter().write(select_query_result);

Kindly suggest how this can be done...
