hi, what’s wrong here?
this is the error message:

cannot access net.java.games.jogl.GLEventListener
bad class file: .\jogl.jar(net/java/games/jogl/GLEventListener.class)
class file has wrong version 48.0, should be 47.0
Please remove or make sure it appears in the correct subdirectory of the classpath.

Jogl was built using java 2 sdk 1.4 if i am not wrong.

So the minimun requirement would be Java 2 Sdk 1.4 upwards :slight_smile:
