Validating if file exist after download

[ttran]

SmartGWT Power

On the client side have a link (button) to download a file. I used Window.open(...) to force download the file. But once I give control to a different browser window, I am out of the loop. I want to know if I can put in a timer of something to better to check with an input file type or javascript to validate that my download is successful.

TIA,

No, not really. The only way to detect succes would be to add a servlet that downloads the file (instead of letting your web server / application server do it) and detect completion when you have succesfully delivered the last byte.
