The easiest way to get eclipse working with opengl is the following:

1) Import core.jar opengl.jar and jogl.jar, then add them to the build path.
2) Extract all the native jogl jars in the opengl directory to a separate directory.
3) Right click on jogl.jar in eclipse and goto properties under native libraries click on external folder and select the folder you extracted all the native opengl stuff to.

this worked for me.

And I had to also add the gluegen-rt.jar to the project build path (and setup it's native libraries) in order to get the project to run. Just in case anyone else is hitting the same wall. Happy New Year everyone.

All the best!

Hey,
I have the same problem.
I working with eclipse Version: 3.4.1 on Windows XP.

I add already the opengl.jar etc. packages.
my be I forgot to include something?
can anybody help?
Thanks Max

After parsing through all these messages, I was able to piece together a solution to getting OpenGL running in a PApplet, in Eclipse 3.5.1, on Windows. So that others don't have to go through what I went through to figure it out, I'll tell you exactly what I did:

1. Create a new Java project
2. Right click on the project root and add a new folder named "lib".
3. Right click on your new folder and create a new folder inside of it called "opengl-natives".
4. Right-click on your "lib" folder and choose "Import".
5. Browse to your "Processing\lib" folder and import the following file:

- core.jar

6. Right-click on your "lib" folder and choose "Import".
7. Browse to your "Processing\libraries\opengl\library" folder and import the following files:

- gluegen-rt.jar
- jogl.jar
- opengl.jar

8. Right-click on your "opengl-natives" (which is inside your "lib" folder) and choose "Import".
9. Browse to your "Processing\libraries\opengl\library" folder and import *ALL* files, *EXCEPT* the following:

- gluegen-rt.jar
- jogl.jar
- opengl.jar

10. In your project's "lib" folder, right-click "gluegen-rt.jar" and choose "Properties".
11. Under "Native Library", click "Workspace" and browse to "YourProjectName/lib/opengl-natives" and click "OK".
12. In your project's "lib" folder, right-click "jogl.jar" and choose "Properties".
13. Under "Native Library", click "Workspace" and browse to "YourProjectName/lib/opengl-natives" and click "OK".
14. Run this as your main class:

import processing.core.*;
import processing.opengl.*;
import javax.media.opengl.GL;

@SuppressWarnings("serial")
public class MyApp extends PApplet
{

public void setup()
{

size(800, 600, OPENGL);

}

}

The key things to note here are that your core JAR files are *not* in the same folder as their respective natives, and that, and for Windows, the DLL files absolutely must be in with these natives.

The instructions from letsgooutside were super helpful and I finally managed to get PGraphicsGL working in Eclipse. I had to find a copy of 1.0.3 in order to create the applet instance within my own JFrame, but once that was resolved it runs fine.

Now that I have created this nice template project for future use, I want to make sure I can export everything properly. However, when I simply attempt to export a fat jar of the project and run it at the command line, I get an UnsatisfiedLinkError:

Code:

TLDR: Has anyone got a good solution for exporting Processing based OpenGL projects from Eclipse?
