title: Struts: Upload a file with progress bar
body: <p>i want to upload files with Struts using the org.apache.struts.upload.FormFile but i would like to put a progress bar (like the gmail uploads forms or some like that), to upload the file (the files are big like 100Mb so the user must see what's going with the application). How i can do it?</p>
  
  <p>Regards :)</p>
