Anyone knows how to use STARFIRE?

Question

I got problem ro manipulate the transform group got from the getModel() method.
It turn out that all the methods such as setScale() and rotX() do not work in such TransformGroup.
My code is as follows:
public TransformGroup load(String _filename) throws Exception
     Inspector3DS loader = new Inspector3DS(_filename);
     loader.setLogging(true); // turns on writing a log file
     loader.setDetail(7); // sets level of detail of report log
     loader.setTextureLightingOn();
loader.parseIt();
     return loader.getModel();
Part of another method:
TransformGroup group = new TransformGroup();;
try
     group = loader.load("E:\\semi3ds\\a3dsemi.3ds");
     group.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
     group.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
     group.setCapability(TransformGroup.ENABLE_PICK_REPORTING);
     Transform3D t = new Transform3D();
     t.setScale(0.0001);
     t.rotX(.5);
     group.setTransform(t);
     catch(Exception e)
          e.printStackTrace();
     }

Hey,
I have found a solution to our problem... :)
For some reason it is not enough to set the Transform3D of the root TransformGroup - the transformation is not propagated through the whole model in this case. It might be a bug of java3d or 3dmax somehow locks the transformations.
In my scenario I needed to change just the scale, so this snippet worked for me - it could be more complicated in your case:
     private TransformGroup testLoader() {
          com.mnstarfire.loaders3d.Inspector3DS inspector =
               new com.mnstarfire.loaders3d.Inspector3DS("D:\\3dmax\\meshes\\server.3ds");
          inspector.parseIt();
          TransformGroup groupModel = inspector.getModel();
          Transform3D transform = new Transform3D();
          transform.setScale(1/Scene.SCALE_FACTOR);
          traverse(groupModel.getAllChildren(), transform);
          return groupModel;
     private void traverse( Enumeration nodes, Transform3D transform ) {
          while(nodes.hasMoreElements()){
               Object node = nodes.nextElement();
               if( node instanceof Group ) {
                    if( node instanceof TransformGroup ) {
                         ((TransformGroup)node).setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
                         ((TransformGroup)node).setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
                         ((TransformGroup)node).setTransform(transform);
                    Group group = (Group)node;
                    this.traverse(group.getAllChildren(), transform);
     }I hope it helped,
