                $.ajax({
                    type: "POST",
                    url: "RecordHandler",
                    data: dataString,
                    success: function(data){  
                        console.log('Add');
                        $('body').html(data);
                        $('body').prepend('<div style="width:100%;text-align:center;"><h3 style="color:green" >Record Added Succesfully</h3></div>')
                    }
                });  

            });

and here is my servlet code......

  private static String UserRecord = "/list.jsp";

  protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{

    String redirect = "";
    String action = request.getParameter("action");
    if (action.equalsIgnoreCase("insert")) {
      String id= request.getParameter("id");
      int uid = Integer.parseInt(id);
      RecordBean record = new RecordBean();
      record.setId(uid);
      dao.addRecord(record);
      redirect = UserRecord;
      request.setAttribute("records", dao.getAllRecords()); //Is it good approach to set request attribute in ajax based servlet?
      System.out.println("Record Added Successfully");

      RequestDispatcher view = request.getRequestDispatcher(redirect);//Is it good approach to redirect request in ajax based servlet?
      view.forward(request, response);
 }

When you call a servlet via AJAX, you stay on the same page by definition, regardless of the headers sent by the server.

If you want to change the page, you must do it with javascript, in the success handler function for the $.ajax(..) call.

You can read the Location response header and set the window.location.href to that value. See here for other options.
