Wich JOGL version are you using?

#3

JOGL 1.1 beta 05 release build

…

Sorry, this is a bug in 1.1 b05 that GKW just fixed. You can see the fix in the CVS repository in src/net/java/games/jogl/impl/windows/WindowsGLContextFactory.java. The fix will be present in 1.1 b06.

The bug I fixed was related to using a shutdown hook. This is related to loading the jogl native dll. I am guessing that you don’t have the proper security permissions set. I bet netbeans provides the correct permissions automatically.

Do you have some sample code that includes the JOGL download in the APPLET tag of the jar file that works for various platforms.
