This example is terribly out of date. There is no longer a
GLCanvas canvas = GLDrawableFactory.getFactory().createGLCanvas( new GLCapabilities() );
call.

You have to start your program with configured native libraries. This means you have to add 1
| -Djava.library.path=<path/to/jogl/natives/folder>:<path/to/gluegen-rt/natives/folder> |
to the command line starting your app. If you use an IDE add this to the JVM-ARGS parameter in your IDEs run configuration. If you use NetBeans, you can try our OpenGL Pack. If you haven't already, read the JOGL User's Guide. It also describes an alternative configuration option that involves modifying your systems CLASSPATH and PATH/LD_LIBRARY_PATH environment variables, which might be less cumbersome if you use the commandline instead of an IDE. |

I finally got it working, turned out while trying to install about 5000 times over and over I had left some old jogl.jar files in another of my classpath so I still got the unlinked-blabla-error. When I removed them everything worked ^_^

Btw I think this should be included somewhere in this topic, maybe in the first post  http://fivedots.coe.psu.ac.th/~ad/jg2/It's the best tutorial I have found by far after several hours of searching. |

This usually happens if you either don't have the gluegen-rt.jar on your classpath or you have a conflicting jogl/gluegen installation somewhere in your system directories like jre/ext, C:\windows\system32 etc. Make sure you only have one installation of jogl/gluegen on your system in a dedicated (non-system) directory (e.g. "C:\development\jogl", "/home/<user>/development/jogl" or something like that) and either setup your environment variables accordingly or start your app with the right commanline options (see above)

Hi. I am a beginner in JOGL and I was trying out some tutorials I got from nehe.gamedev.net (for c / c++).. I hit a snag when I was doing the 3d shapes tutorial, the tutorial says, that we need to move the drawing point to the loc (-1.5, 0, -6.0), using glTranslatef() func. I tried the same but I am getting just a black screen. I tried the code without changing the drawing point, i.e leaving it at its original place (0, 0, 0), then I could see a very big pyramid rotating. Here is the code. I am using eclipse, with the latest JRE and JOGL library. Can somebody please tell me, what I am doing wrong.  Thanks in advance. 1

You need to set up your projection matrix.

Take a look at the SimpleJOGL example some post above, and copy the reshape()-method to your SimpleEventListener class. Also the Animator should not be instantiated and started inside the init() callback. Chances are, that init() is called multiple times on e.g. window resize and you would instantiate and start multiple animators this way, which could lead to an application freeze. Again, take a look at the SimpleJOGL example.

Hi, I've read this thread and googled around, but I'm having a problem getting JOGl to run in an Eclipse project. I've followed the instructions here: http://www.geofx.com/html/OpenGL_Eclipse/OpenGL_Eclipse.htmlto make a simple Eclipse RCP application with a single View that implements GLEventListener, and basically the project builds OK, but when I run it I get the following exception: java.lang.NoClassDefFoundError: javax/media/opengl/GLEventListener Now, I have a directory called "C:\jogl-1.1.1-windows-i586" which is an unzip of the jogl-1.1.1-windows-i586.zip, and so contains the JOGl dlls and jars, and I have included the gluegen-rt.jar and jogl.jar from here in my Eclipse project. As I say, Eclipse is happy with this and the project builds fine, and it can 'see' javax/media/opengl/GLEventListener, but it fails at runtime. I have tried adding "C:\jogl-1.1.1-windows-i586" and the "C:\jogl-1.1.1-windows-i586\lib" subdirectory to my Path environment variable, but I get the same error. Any help would be appreciated. |

Right, I've solved this now. For anyone with a similar issue, here is my understanding of the situation: To recap, I'm trying to get a minimal JOGL example working in an Eclipse RCP application. The application compiles fine, but craps out at runtime with "java.lang.NoClassDefFoundError: javax/media/opengl/GLEventListener". This seems like typical classpath fun and games, so I fart around and set my CLASSPATH environment variable (I'm on Win XP) to include the world and his wife, but of course it still doesn't work. I try putting all the JOGL crap in the "\jdk1.6.0_01\jre\lib\ext" directory. This not only doesn't solve the problem, but now it won't even build (Eclipse complains about Access Restriction on the JOGL stuff; great) - I know putting the JOGL stuff in here is naughty but I'm just trying to get it to work, so w/e. What I didn't realise is that Eclipse ignores the CLASSPATH variable, so messing around with that is a waste of time. My understanding was that if you included a JAR in the Project > Properties > Libraries > Add External Jars bit, then Eclipse would sort out the CLASSPATH stuff for you, and certainly it adds some stuff to its little .classpath file, but it doesn't work at runtime, so there you go. Anyway, I think this is some special wierdness of making an RCP application. I think you have to do Other Things to get the CLASSPATH sorted for external JARs in an Eclipse RCP application. Here's what I did: Start a clean RCP Plug-In project in Eclipse. Add a lib directory to it. Put the gluegen-rt.jar and jogl.jar in there. Right-click on them in Eclipse and do 'Add to Build Path'. Right-click your MANIFEST.MF file and do 'Open With' > 'Plug-in Manifest Editor'. In the Manifest Editor select the Runtime tab. On there, under the Classpath bit click 'Add...', and select your lib/gluegen-rt.jar and lib/jogl.jar. That's it really. This is basically following the steps here: http://dev.eclipse.org/newslists/news.eclipse.platform.rcp/msg06980.htmlTo see some JOGL stuff, add a View and if you use the code from here it should work: http://www.geofx.com/html/OpenGL_Eclipse/OpenGL_Eclipse.htmlHope this is helpful to someone. |

I'm getting an error similar to the one listed a couple of posts above. I've double-checked and there is only one instance of the gluegen-rt.jar file on my system and it is in the same directory as my jogl.jar file (which Java is finding correctly).
Here is the command I'm running and here is the error:

you forgot to add gluegen-rt.jar to the classpath.
c:\JOGL\Examples>java -Djava.library.path=c:\jogl\native -classpath c:\jogl\jogl.jar;c:\jogl\gluegen-rt.jar;. SimpleJOGL

That would be it. Thanks! Isn't there a better way to set that somehow? At least now I can play around with stuff. Thanks again.

You could add the jars to the CLASSPATH environment variable and the directories with the native libraries to the PATH. Oh and also read the "Jogl Users Guide" ;-) |

(the whole thread is deprecated regarding JOGL2, its an introduction to JOGL1. Maybe a moderator should detach the thread from being the first in this forum)

I have a problem: I can't find the jogl.jar file! I (finally) suceeded in building Jogl, and in the jogl\build folder i have 3 other folders:
jogl, nativewindow, newt.
In the jogl folder, I have a whole list of jogl.XXX.jar files but never the simple jogl.jar file...
Because of this, I cannot run the simple System.loadLibrary("jogl"); command...
Any advice?

Im sorry but i am horribly confused about creating and binding a context to GL! What exactly is the recommended Window ToolKit? In the FAQ you can read, awt and swing are bad but i cant get the native Window toolkit running. http://kenai.com/projects/jogl/forums/forum/topics/1691-How-to-create-a-native-window- <- i found this here where you can see how to create a native window. But i have no idea how to get a GLDrawable out of the window in order to add it to an Animator. If this question doesnt belong here please forgive me! Since this is my problem with the "getting started" part. |

Hello , I'm developing the applet http://analisegrafica.net/applet.html. Some people report Java can't find the Main class, but it works on my Windows and Linux environments. I checked browser/Java/SO versions and all was equal to mine. What's wrong? Should I use JOGL 2? Is there a specific Topic about? Is there a Netbeans plugin for JOGL 2? Thanks  |
