JOGLAppletLauncher beginner issue

When i try to test the JOGLAppletViewer on https://jogl-demos.dev.java.net/applettest.html I get


Error:Start failed:class not found:demos.applets.GearsApplet

I’m working with linux, can somebody help me?

What version of the JRE are you running? Have you installed for example JRE 5 from http://java.com/ ? Do the sample applets at http://java.sun.com/products/plugin/1.5.0/demos/plugin/applets.html work?

when i type :


java -version

I get:

Java™ SE Runtime Environment (build 1.6.0-rc-b104)
Java HotSpot™ Client VM (build 1.6.0-rc-b104, mixed mode)

sorry, wrong button,

The examples at http://java.sun.com/products/plugin/1.5.0/demos/plugin/applets.html seem to work allright.

It is solved, I just upgraded to 1.6.0-b105.
