Java EE (Java Enterprise Edition) General Discussion

Hi! I would just like to ask if it's possible for me to check the status of a file download using jsp/javascript.
I have a jsp page with a button, which when clicked, opens a 'Save As' dialog box for downloading a file from the server (file content is retrieved from db). I want to refresh or redirect my page after the download is complete. Is that doable?

Thanks in advance, any help will be greatly appreciated. :)
