If the content-length http header is appropriately set by the browser when uploading files over http, you can implement an AJAX based progress bar for uploading files:
There is a java blueprints jsf component that does this (AJAX FileUpload) https://blueprints.dev.java.net/ajaxcomponents.html also here is an article I found that describes how to implement the same... http://today.java.net/pub/a/today/2006/02/09/file-uploads-with-ajax-and-jsf.html Bill On 6/11/07, ::SammyRulez:: <[EMAIL PROTECTED]> wrote:
My speculations told me that HTTP multipart file send are not suitable for sending files larger than 100MB over a lan and 20 MB over the internet. I'm not saying it is not possible, nor that someone could have done it right.. but 200MB are a lot of data and need serius recover chacksum and so. I suggest you to find better ways to move the file. 2007/6/11, Andrew Robinson <[EMAIL PROTECTED]>: > I don't think there is a why to show progress for file upload.
