Copy the applet (all files from this folder) in a web/http server.
Replace http://server/ and http://bonzaiengine.com/jws/ by the url of the applet in those files:
 * applet.jnlp
 * bonzaiengine.jnlp
 * jogl.jnlp
To run the applet, use applet.html file.

Note:
applet-local is an example of the applet running in a local server.
All applet files was copied in http://127.0.0.1:8888/bonzaiengine/applet/applet-jogl/
and jogl and bonzaiengine jnlp extension was reused from http://127.0.0.1:8888/bonzaiengine/jws/
(which shows how to easily re-used jogl/bonzaiengine between multiple applets)
