jQuery.get(servlet url) should activate Java servlet?

in Getting Started • 12 years ago

I am trying to develop a web program that uses ajax with AppEngine.

in HTML <head> part, I put...

function asyn() {

$.get("http://localhost:8888/ajaxtestforpictures");

}

//]]</script>

and the java servlet is only...

public class AjaxTestForPicturesServlet extends HttpServlet {

public void doGet(HttpServletRequest req, HttpServletResponse resp)

throws IOException {

resp.sendRedirect("redirected.html");

}

the URL of the servlet (/ajaxtestforpictures) is fine.

I am hoping that clicking the button would activate the servlet and redirect to redirected.html. But it does not work. I have recently started using jQuery.ajax, so could anyone help me out to find the problem?

Have you included the jQuery library?

Wrap your function in a $(document).ready(function() {
// put function here
});

Thanks for your reply.

But I certainly have the jQuery library,

which should be good enough. Also I had some other simple jQuery codes work without problem, so the library is not the issue.

I have wrapped the code as you described, but no difference.

$(document).ready(function() {

$(function(){

$(".login").click(asyn);

});

function asyn() {

$.get("http://localhost:8888/ajaxtestforpictures");

}

});

and for the HTML <body>,

<a class="login" href="#">redirect</a>
