Ewald,
Seens your install miss the native Java3D libraries.
check if you have the file libJ3D.so
in the folder
/usr/j2se/jre/lib/sparc/
I guess you will need also libJ3DUtils.so and
libJ3DSound.so in the same folder above.
The Unixe's *.so are equivalent to Window's dlls.
Do not worry, your Ja
I'd check that OpenGL installed.
"glClipPlane" is defined in /usr/openwin/lib/libGL.so.1 on my system:
nm /usr/openwin/lib/libGL.so.1 | grep glClipPlane
[4708] |359444| 72|FUNC |GLOB |0|10 |glClipPlane
libJ3D.so has a dependency on libGL.so.1
$ ldd libJ3D.so
libdga.so.1
