Problems when compiling JOGL

Hi,

I wanted to compile JOGL (1.1.1) to get the GL.java but I got the following error:


build.static.gl:

     [echo] BuildStaticGLInfo has been built successfully.

declare:

build.static.gl.task:

     [echo] StaticGLGen ANT task has been built successfully.

java.generate.check:

java.generate:
     [echo] Generating GL interface class
  [gluegen] java.lang.NoClassDefFoundError: antlr/TokenStreamException
  [gluegen] Exception in thread "main"

BUILD FAILED
C:\Dokumente und Einstellungen\Christoph\Desktop\gl\jogl\make\build.xml:1071: The following error occurred while executing this line:
C:\Dokumente und Einstellungen\Christoph\Desktop\gl\jogl\make\build.xml:470: GlueGen returned: 1

I followed the instructions in the HowToBuild.html but I still have no success.

Could you help me, please?

Could anybody of you post the GL.java (Version 1.1.1), please?
