font-family:Arial'> I
am working on jsp’s and have an issue in uploading files. I am allowed to
upload at the max of 20MB on the server, but the issue is often user ignores
the message and tries to upload more than 20MB. The request goes to the server
and the server then throws an error message. This process however takes some
time to get executed. I would like to have a client side validation done for
the size of the file. To do this I cannot use ActiveX objects as the business
requirements strictly restricts use of ActiveX Objects. The other option is to
use the following code :<o:p></o:p></span></font></p>
