Compile error with JOGL

Question

I try to compile a simple Java program with JOGL OpenGL, from the command line. In the Eclipse all works fine, when I compile it from the command line with javac I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/opengl/GLEventListener
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClassCond(Unknown Source)
...
Caused by: java.lang.ClassNotFoundException: javax.media.opengl.GLEventListener
...
Could not find the main class: SimpleScene.  Program will exit.

I already add to -classpath all the .jar files I find in JOGL directory. The Makefile to build the program is the following:

SimpleScene:
  javac -Xlint:deprecation -classpath  \
  $(jogl)/joal.jar:\
  $(jogl)/jogl.os.x11.jar:\
  ...
  $(jogl)/nativewindow.awt.jar:\
  $(jogl)/jogl_cg-natives-linux-i586.jar:. \
  SimpleScene.java

Answer 1

I had a similar problem and figured out my simple mistake. GLEventListenere is an interface ; not a class.

I fixed my problem after realizing this because my code that uses GLEventListener should use the keyword 'implements' instead of 'extends'.
