Hello all,

In JSP / HTML, I want to restrict the size of file being uploaded.

<input type="file" name="myfile"/>

If the size of file more than a specific size say 5MB, i want to give mesage to the user. I don't want to wait till the file gets uploaded to server and then validate the file size. I am looking for client side validation. Can it be done using scripting language or any other way?

I need a solution for this in Internet Explorer. I got a solution using ActiveX control:
var myFSO = new ActiveXObject("Scripting.FileSystemObject");
var filepath = document.getElementById('myfile').value;
var thefile = myFSO.getFile(filepath);
var sizeInBytes = thefile.size;

But ActiveX controls are not allowed in our application. Is there any alternative way for this?

Please suggest the possible ways.. Thanks!!

activex is the only way to do it in IE that i know of...

Thanks rnd me. Is it possible using Applets?

I've used applets and it worked.

jFileUpload solved this issue:
http://www.jfileupload.com/products/jfileupload/ => download link
http://jupload.sourceforge.net/howto-customization.html => documentation
* http://www.jfileupload.com/products/...tion_http.html => config params

maxsize- This parameter identify the maximum size of the uploaded file. It prevents the user to upload too big files.

thanks to the forum for the suggestions.
