Vaadin File chooser

Hello All,
 
In My vaadin based web app , I need to upload videos and Images to Amazon s3 . So with the current vaadin version  there is noway to upload files to amazon s3 location(with vaadin File Upload  we can only upload files to local server ?).

I already developed the file uploading part with hardcoded file path . what I need is some simple file chooser that I can get the actual file path to replace hard coded  one . Is there anyway.

Or Is there anyother way to do this ? 

Thank you
