In case your Java Plugin supports JNLP, the jogl-applet-runner-newt.jnlp is used, otherwise it shall fallback to JNLPAppletLauncher.

Note that it is important for the startup time to have the same JVM arguments in the applet tags, as well as within the JNLP applet description, here see property sun.java2d.noddraw.
Only if JVM arguments of the JNLP applet description are satisfied by the applet tag's JVM,
the plugin will not need to start a new JVM. OF course, the applet tag's JVM spec may exceed the JNLP applet's one.

JOGL NEWT JNLP Applet Runner Special Keys:

- d - toggle decoration
- f - toggle fullscreen
- r - in/out browser window
- a - on/off always-on-top

The applet above is instantiated with the following code:

Note that the jogl-test.jar, which contains the test applet class, does not need to be signed! JogAmp Community signs applet-launcher.jar, jogl.jar and gluegen-rt.jar, which contain the JNLPAppletLauncher and JOGL's supporting classes; this is the only Java code which needs to be signed in order to deploy applets using JOGL and is the only certificate the end user must accept.

The JNLPAppletLauncher home page contains more information about what files must be placed on the web server in order to enable the deployment of applets using JOGL and other extensions.
