> I'd like to have a way to have a configurable upload listener to be used by JakartaMultipartRequest so any application can monitor the progress of a file upload without having to write own uploader classes or using any plugins
> listener can be attached to the uploader on the following lines on per upload basis
>    88               ServletFileUpload upload = new ServletFileUpload(fac);
>    89               upload.setSizeMax(maxSize);
> e.g.
> String monitorKey  = request.getParameter("UPLOAD_MONITOR_KEY");
> if (monitorKey  != null){
>     //Create a progress listener using the configuration information, this is what I need from this feature request
>     ProgressListener progressListener = createProgressListener();
>     upload.setProgressListener(progressListener );
>     request.getSession.putAttribute(monitorKey  ,progressListener );
>    //Now the application will be able to monitor the upload progress asynchronously
>
