So you're gonna force me to waste another 5 minutes of my life waiting

How can you find out the size of the file you want to upload ?

What I meant was "You as the app developer set the value in web.xml" and
therefore you know what it is."
And therefore you don't have to find it at runtime you already know it,
so if want to
display the value just hard code it.
I don't think you are going to be able to do anything on the client to
prevent an
oversized file from being uploaded.
Are you sure this code is still throwing exceptions ?
Alot has changed, if "132" is any indication of when this issue was posted.
