drag-and-drop forms html javascript servlets

How to submit drag and drop images without Ajax to servlet?

I’ve an array of images got from drag and drop using HTML5 and previously was submitting those through ajax.

But now I want to send these in a form WITHOUT using ajax.
What would be the approach? thanks in adv.!!

function upload(file) { // image file from drag n drop 
var formData = new FormData();
formData.append("file", file);
var xhr = new XMLHttpRequest();"POST", "uploadServlet", true);
