Sending value from javascript to jsp (with jquery)

right now I have a jsp page that allows you to sort some elements when they are ready, and clicked the link, the javascript function converts all the information into xml (text in a variable), after that I need to send this xml to on the jsp page again, I tried put information in hidden input and submit the form, sending with $ .post and a few more jquery functions, but nothing worked. Any ideas?

in my JSP I read a message like this:

<% out.println(request.getParameter("data")); %>

This does not work:

xml = "<xml></xml>";
$("#form").submit(function(){
   alert("JS: " + $("#data").text());
   $("#data").text(xml);
});

It's the same:

xml = "<xml></xml>";
$("#data").text(xml);
$("#form").submit();

replacing .text with .html does not work

Any ideas are welcome, thanks

jQuery Ajax API - GET POST, - .

You can always use XMLHttpRequest to send data. This can be done without our interaction with the user, for example, with the submit form button. jQuery has built-in functions to support such queries.
