title: Custom file picker without using <input type="file"/>
body: <p>I am working on a java-based (webwork framework) web-app where the file to be uploaded needs to be compressed first. Since there's no way to set the value of "input type='file'" element via javascript, I decided to take the route of an embedded applet. Basically this applet compresses the chosen file, then uploads the compressed file to the server via scp.</p>
  
  <p>It worked well, but I have issues regarding the rendering of the web page itself. I am thinking instead of implementing the file picker within the applet, if there's an existing file picker that I can use instead. Of course without putting any "input type='file'".</p>
  
  <p>Links to these existing custom web file pickers will be very much appreciated.</p>
