Hi,

I am developing an applet for some OpenGL ES stuff using JOGL. In eclipse I can start the applet but in the browser I have trouble because the java console prints a NoSuchMethodError in my line where I create an instance of GLCanvas.

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

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

glCanvas = new GLCanvas(caps); // throws NoSuchMethodError

Exception in thread "thread applet-de.beuthhochschule.bachelor.martin.Benchmark-1" java.lang.NoSuchMethodError: javax.media.opengl.awt.GLCanvas.<init>(Ljavax/media/opengl/GLCapabilities;)V
   at de.beuthhochschule.bachelor.martin.Benchmark.initComponents(Benchmark.java:60)

   at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Plugin2Manager.java:1620)
   at java.lang.Thread.run(Thread.java:662)


I created a jar with and without the jogl.all.jars (and gluegen, nativewindow and newt) but it just didn't work.
Does someone have an idea?

Might be security related.  If you haven't already, try signing all the jars.

I tried that, but nothing changed, the exception is the same.
I also make sure by looking in the JOGL API that the constructor I use is really there.

I made a pastbin of the java console: http://pastebin.com/xjk84pTV

update
As I asked on stackoverflow, too, I just link to the solution: Jogl Applet with JNLP runs in eclipse but not in the browser
