public class JUploadApplet
extends JApplet

The applet. It contains quite only the call to creation of the JUploadContextApplet, which contains the technical context. This context is responsible for loading the relevant UploadPolicy.

The behavior of the applet can easily be adapted, by :

Using an existing UploadPolicy, and specifying parameters.

Creating a new upload policy, based on the DefaultUploadPolicy, or created from scratch.
For all details on this point, please read the howto-customization.html page.
