<title>JOGL JNLP Applet Test</title>
</head>
<body>
<P>
In case your <a href="https://jdk6.dev.java.net/plugin2/jnlp/">Java Plugin supports JNLP</a>,
the <em>applet-gears.jnlp</em> is used,
otherwise it shall fallback to <a href="http://jogamp.org/applet-launcher/www/">JNLPAppletLauncher</a>.
</P>
<P>
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 <em>sun.java2d.noddraw</em>. <br>
Only if JVM arguments of the JNLP applet description are satisfied by the applet tag's JVM,<br>
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.
</P>

<P>
Note that the jogl-demos.jar, which contains the GearsApplet class,
<B>does not need to be signed</B>! 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.
</P>
<P>
The <a href="http://jogamp.org/applet-launcher/www/">JNLPAppletLauncher
home page</a> 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.
