Thank u very much for your answer.
I solved the previous problem (caused by the bad setup of the classpath) but
now another one occurs:
No skin defined in xj3d-skin.properties
Producing default properties.
Exception in thread "main" java.lang.NoClassDefFoundError:

I'm using Xj3D 1.0
What's the solution to this problem?
Thank very much for your help!

The jogl library is either - not on your classpath, or not installed on
your system. The set of requires libraries is listed here:

http://www.xj3d.org/tutorials/xj3d_application.html

also note that jogl requires a native library.

I downloaded the jogl zip file but i haven't a setup.exe file. I have copied
the files in zip file in the directories /bin and /lib of my XJ3d directory.
I also modified my path and classpath variables including the directories
/bin and /lib but the problem persits.
Have you other idea?
Thanks very much

Perhaps a version mismatch between the Xj3D and jogl releases? jogl was
repackaged for the JSR-231 releases. If you downloaded one of the JSR
releases and used it with Xj3D 1.0 - that would cause a no class def
found exception even with the jogl jar on the classpath.

If the Xj3D you have is from a development snapshot, or the release
package - there should be compatible jogl libraries included. If you
have downloaded the Xj3D source and then loaded the jogl package
separately - the last release build before the JSR crossover should be
compatible.

Instead...I think I need the package net.java.games.jogl.* but i haven't it.
I'm looking for this package but i don't find it. If you have this file, can
you send me it by email please?
Thanks!

Perhaps you have reason beacusa if I unjar the file I found a
javax/media/opengl path to find GLEventListener.class instead of
net/javagames/jogl.
So, I try to download an oldest version oj jogl....pray for me :-)
