Re: visualizing upload/download status in a statusbar

[soapergem <so...@gmail.com>]

Hi,

I am very new to Java but have been trying to create a web applet that can
upload a file with a progress bar and requires no server-side Java to keep
track of how many bytes have been sent. Is this possible with this
"CountingRequestEntity" class? If so, could you please include some complete
example code of how this would be achieved? Also, you said that you are
unable to determine the total number of bytes that are being sent, but if
you have selected a File object representing the file to upload, can you not
just use File.length() to determine the total number of bytes? Thanks much.

Regards,

Gordon
