Hi,

I have tried dozen ways of creating an applet with JOGL but the result is always the same: I get a NoSuchMethodException when I try to create an instance of GLCanvas.

Java code:

GLProfile glp = GLProfile.get(GLProfile.GL2ES2);

GLCapabilities caps = new GLCapabilities(glp);
caps.setSampleBuffers(true);
caps.setNumSamples(8);

glCanvas = new GLCanvas(caps); // crashes here, worked when started as applet in eclipse

My applet code

<applet code="org.jdesktop.applet.util.JNLPAppletLauncher"
      width="660"
      height="500"
      archive="http://jogamp.org/deployment/util/applet-launcher.jar,

   <param name="java_arguments" value="-Dsun.java2d.noddraw=true">
   <param name="jnlp_href" value="applet-benchmark.jnlp">
</applet>

My JNLP code:

<?xml version="1.0" encoding="utf-8"?>
<jnlp href="applet-benchmark.jnlp">
    <information>
        <title>WebGL-Benchmark</title>

        width="660" 
        height="500">
    </applet-desc>
</jnlp>

And finally the java console output (its too much, so I used pastebin): http://pastebin.com/xjk84pTV

I am totally lost...

*edit*
Before asking: When I use the JNLP of the GEARS demo, I can see the demo applet. So basically it should be working...
