Martin,
It's unclear from your message if you tried to:
1) Literally "SCALE" your object in Z only, or
2) Transform your object, or
3) Transform your viewpoint.
Either #2 or #3 would work for you. If you are applying the transform to
your object, then set the Z value to a more negative value than it
currently has. If you are transforming your viewpoint, set the Z to a more
positive value than it currently has.
You can also try this (where "myUniverse" is defined as your SimpleUniverse):
myUniverse.getViewingPlatform().setNominalViewingTransform();
You may also want to try setting your near and far clip planes. Remember
the units in Java3D are in meters so if your VRML file is in millimeters
you are likely inside a very, very large object and may not see it even
with the nominal viewing transform (I believe) due to the clip plane values.
If this is the case you can either adjust the clip planes or scale down
your object (similar to #1 above, but in all axes).
