java.lang.NoClassDefFoundError: javax/media/opengl/GLJPanel

Hi,

I am trying to use the API to plot a 3d scatter chart.

This is the code I am using:

Coord3d[] coords = new Coord3d[32*32*32];

org.jzy3d.colors.Color[] colors = new org.jzy3d.colors.Color[32*32*32];

for(int i = 0; i < 32*32*32; i++){

    int point = LUT[i%32][(i/32)%32][i/(32*32)];

    Color color = new Color(point);

    coords[i] = new Coord3d(color.getRGBColorComponents(null));

    colors[i] = new org.jzy3d.colors.Color((i%32)/31f, ((i/32)%32)/31f, (i/(32*32))/31f, 0.25f);

}

                    

Scatter scatter = new Scatter(coords, colors);

Chart chart = new Chart(Quality.Nicest, "swing");

graphPanel.setLayout(new BorderLayout());

graphPanel.add((JComponent)chart.getCanvas());

If I am using the latest version of jzy3d and the dependencies available from the website I get an error that says: java.lang.NoClassDefFoundError: javax/media/opengl/GLCapabilitiesImmutable

One of the other topics suggested downgrading to the 0.8.x version. After I did (and got the respective dependancies) I get the following error:

I have JOGL included in the path, so I don't understand why this is happening. Any help would be appreciated.

Hi,

com.jogamp.opengl.awt.GLJPanel is part of jogl 2.3.2 used by jzy3d 1.0.0

javax/media/opengl/GLJPanel is part of jogl < 2.3 and used by jzy3d < 1.0.0

Ensure you have both 1.0.0 and jogl 2.3.2 in your classpath.

I had tried this before, but it didn't seem to work... It's working now though, thanks :D
