jquery - web client to get progressive server response - how to? -


been trying this, perhaps efforts not heading right, appreciate help.

my html page has button , div. when click button, server has keep pushing numbers couple of seconds interval, , server pushes numbers, need them on div, progressively, in-synch server's status. how achieve this? tried using asynccontext, behaves similar response , flushes whole output @ end not want.

protected void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {     response.setcontenttype("text/html");     asynccontext ac = request.startasync(request, response);     ac.start(new runnable() {         @override         public void run() {             (int = 1; <= 5; i++) {                 try {                     ac.getresponse().getwriter().print("hello-"+i);                     system.out.println("written hello");                     thread.sleep(3000);                 } catch (exception e1) {                     e1.printstacktrace();                 }             }             ac.complete();         }     }); }

and html below:

<html> <head>  <script src="../js/jquery/jquery.js"></script> <script>     function ajax_stream() {             var xhr = new xmlhttprequest();             xhr.onreadystatechange = function() {                 $("#mydiv").text($("#mydiv").val+xhr.responsetext);             };             xhr.open("get", "../test", true);             xhr.send();     } </script> </head>  <body>  <button onclick="ajax_stream();">start ajax streaming</button>  <div id="mydiv">starting : </div> </body> </html>

not sure if understanding on concept correct, progressive state of server response captured client trying achieve.
