you want perform ajax call instead of submitting form. build javascript function e.g. using jquery:
$.post("<your servlet here>", $("#y<ourformidhere>").serialize(),callback); where callback function this:
function(data){ console.log("data",data); // want response data } off course have bind $.post function form button.
