IIRC, you have to go to project properties, build path, and add the needed jars to the project.

hello it worked but not with the sketches that uses opengl. I been using pure opengl in processing, i usually load this:
import processing.core.*;
import processing.opengl.*;
import codeanticode.glgraphics.*;
import javax.media.opengl.GL;

and i have this in my setup
 size(600,600, GLConstants.GLGRAPHICS);

and in my draw i have this:
 GLGraphics renderer = (GLGraphics)g;
 GL gl = renderer.beginGL();

so i can access to the opengl commands using the gl variable in this way:
gl.glRotatef(45, 0, 0, 1);

but it doesnt work im getting this error:

To you have to add opengl.jar AND jogl.jar to your building path -> library. And additional you have to set the native library folder of jogl in my case its 'opengl/library'.

Configure Buildpath -> libraries -> Add jogl -> now you see jogl in your libraries -> expand jogl -> native library location
