public class AjaxFlexibleFileUpload
extends AjaxFileUpload

AjaxFlexibleFileUpload is an enhanced file upload component that uses a call to a hidden iFrame to handle a file upload. It is based on the code in AjaxFileUpload but extends it by using Andrew Valums' ajaxupload.js (from http://valums.com/ajax-upload/). This dynamically creates the iFrame at the end of the current page content freeing this component to be used in or out of a form. The component is fully styleable (including the upload button) and supports upload progress and canceling.
