Applet throwing NoSuchMethodException

This post was updated on .

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,
               http://jogamp.org/deployment/webstart/nativewindow.all.jar,

</applet>

My JNLP code:

<jnlp href="applet-benchmark.jnlp">
    <information>
        <title>WebGL-Benchmark</title>

      <jar href="http://192.168.0.39/benchmark.jar" main="true"/>
      <extension name="jogl-all-awt" href="http://jogamp.org/deployment/webstart-next/jogl-all-awt.jnlp" /> 
    </resources>
    <applet-desc 
        name="WebGL-Benchmark"
        main-class="de.beuthhochschule.bachelor.martin.Benchmark"
        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...

looks all great .. however,
since we have changed the API (GLCapabilities -> GLCapabilitiesImmutable).

You need to recompile (w/o source code change) .. sorry about that.

You compiled classes reference
cstr 'GLCanvas(javax.media.opengl.GLCapabilities)',
which is now
cstr 'GLCanvas(javax.media.opengl.GLCapabilitiesImmutable)'

Re: Applet throwing NoSuchMethodException

I can't believe it! I know I checked that the constructor I use is really in the API, but I somehow missed the "Immutable" end...
And the reason why it works in eclipse is pretty simple: My good professor at my university used old JOGL libs where these changes are not yet made.
So I was using old stuff in eclipse while downloading the newest one with the applets... GREAT!

Sven: You saved my bachelor thesis! Really (already made a WebGL Benchmark, now I can finally port the benchmark to Java...)

Anyway, I figured out that the newt.jnlp that can be found here http://jogamp.org/deployment/jogamp-next/ has broken links inside. There is no "newt.x11.jar" it must be "newt.os.x11.jar". I guess you as a maintainer can fix that :)

Thanks from Berlin!
Martin

AWESOME .. can you post URLs and is it open source ?

Would love to add you stuff in our 'collection'.

It might be also great to use your benchmark to test JOGL performance regressions ?

Please share .. thank you.

Oh .. I earmark this, but just in case - please file a bugreport, thx.

Re: Applet throwing NoSuchMethodException

I can post a link to it, of course. Its not really open source but I can publish the code after my bachelor deadline.

The benchmark itself is not very complex and targets the performance of webgl. The java implementation is only there for a reference as how the performance would be with a desktop/applet application. But it can be extended to check the JOGL performance as well, I think.

Anyway I will publish it here, I promise :)

Re: Applet throwing NoSuchMethodException

Hi,

my benchmark for WebGL is ready. The reference implementation with java doesn't really use a lot of jogl so its basically just a reference to webgl than a jogl benchmark, but you wanted to be informed about it anyway.

The link: WebGL Benchmark
