Well, you are not alone. Me and many others have been asking for some way
of saving out scenes directly from J3D with simple API calls for about the
last two years now. Unfortunately, at the moment, there does not seem to be
any easy way to do it, and no one from the Sun J3D-Guys has ever (as far as
I remember) answered to our pleas with some words of encouragement.
Some people have been hand-coding partial serializability for some subset
of the J3D-Classes, AFAIK, but nothing was ever posted to the list.
I (and from what I remember, many others) would even be very happy if it was
possible to save just the geometry and hierarchical structure of a scene in
an easy way, I would not need to have optimized SGs serialized (which is
obviously much harder).
At the moment, I am exploring a new way to solving this problem.
The Swing team has released a new way of saving hierarchies of JavaBeans
describing a Swing GUI using an XML-based descriptive approach which does
not need to save the binary representation of objects using serialization
but rather parses the given hierarchy and writes out a description of the
objects and their values. This can then be used to reconstruct the given
objects and their relations. For a closer look, check out:

Anyway, I am now trying to use this way to describe my scenes. At the moment
it seems as if we would just need some of the Meta-Data describing the J3D-
Objects to be added to the given code to get some basic way of saving out
things. I (and I think some other people here) would be very interested
in reading some opinion from "official voices" for J3D considering this
approach. Could the J3D-Team please take a look at this and tell us what
they think?
Oh, and I think it might be interesting to see how many people are still
interested in some easy serialization of J3D. So, if you are, please react
to this mail and give some comment. The more we are, the easier we might
convince the team that serialization is important for J3D's success.
