Hi I have been trying to pass value from ajax to servlet ,have used JQUERY jquery-1.3.2 & query-1.3.2.min .I am successfully able to send the data but if i print the value in servlet getting null

Here is my js event

<script type="text/javascript" src="js/jquery-1.3.2.js"></script><script type="text/javascript" src="js/myjquery.js"></script><script type="text/javascript" src="js/jquery-1.3.2.min.js"></script><script type="text/javascript">    function AddNext(event)    {       MQA.EventManager.addListener(map, 'click', AddNext);        var lata = event.ll.getLatitude();        var lnga = event.ll.getLongitude();        var latlon=lata+"|"+lnga;        addpasslatlon(latlon);        MQA.EventManager.clearAllListeners( map);        exit();      };   

myjquery.js-

    function addpasslatlon(latlon)     {                      var value=latlon;           $.ajax({             url:'insertPos',             type:'POST',             data:value,             success : function(data){                 alert('success'+data);             }           });    }

MY servlet class-

    public class InsertPos extends HttpServlet {        private static final long serialVersionUID = 1L;        protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException        {            response.setContentType("text/html;charset=UTF-8");            PrintWriter out = response.getWriter();            String a =request.getParameter("value");            System.out.println(a);        }    }

web.xml-
