I think i figured it out.
Let's say i build my own class e.g.

i have to implement SceneGraphIO in order to make this class writeable to the stream.
Otherwise i will get a NullPointerException, right?

I'm developing an app giving the user to register certain visualization

Maybe i refer to the wrong class.

Ok, short tutorial on scenegraph.io.
Scenegraph does not understand pointers. With normal serialization, you
just add a pointer field to class and it get automagically saved to
disk, dereferencing by itself. With scenegraph.io you need to do it
manually.

My current attempt to, just using the usual TextureLoader stuff is not loading the

Are you setting the object's names properly in the hashmap when writing

If so when you read you will retrieve the names and nodes, in the hashmap,
as it is expected...
I guess my solution may not fit your case:

Thanks for the heads up.
I brought up your link on my Win2K/1.5Ghz/512MB here and

Curious, it looks as if Win2k has 10ms granularity where as
Win98 is 50ms(I think I read that earlier). I presume this

I solve this kind of problem this way:
Get the namedObjects ot the scene and put all then in a HashTable.
If course the name of the objects where the keys.
When I want to do some operation in one of that objects returned I just ask
it to hashtable,
check if the returned objects it is a instanceo
