Show Progress of File Upload
Hello
Is it possible to show the progress of a file upload. At the moment I am
using the Tomahawk component t:inputFileUpload but I couldn't see an easy
way to display the progress. The size of my files are around 200M. Are there
other tags that I could use?
Thanks
Daniel

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...

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.

Re: Show Progress of File Upload

I don't think there is a why to show progress for file upload. What
happens in HTTP is that the full request is sent all at once and then
the response is streamed to the client. In the servlet environment,
the servlet is not invoked until the entire HTTP request has been
received and therefore, the full file contents. It really isn't a
matter of JSF, but of HTTP.
If you need to show progress, you will have to use a browser plug-in
of some sort (signed applet for example), or work in the socket layer
in the server. If you have several files being uploaded, you could
send them one at a time using an IFRAME and show progress that way
(each file having its own form that submits to an IFRAME target, and
use the response in the IFRAME with javascript to update some kind of
status, like file 2 of 5 uploaded).
