Upload progress bar Java Servlet?

I want to show upload progress bar for my uploads usin开发者_JS百科g servlet. I tried Ajax, iFrame technique. The page is not reloading and the file also getting uplaoded. But, progress bar is not coming. Is there any jQuery progress plugin available for java servelts?

Thanks!!

I strongly recommend jQuery Uploadify plugin for ajax file uploads. It comes with a progress bar as well. You can find an example on their demo page.

Integration with JSP/Servlet isn't that hard. You can basically keep the servlet code for "regular" file uploads unchanged. I've however ever written a mini tutorial in an answer here (check the "update" part of the answer), you may find it useful as well.
