Adriano,
This simply means that you've added this object to another parent already.
For example, if you have:
TransformGroup tgA = new TransformGroup();
BranchGroup bgA = new BranchGroup();
BranchGroup bgB = new BranchGroup();
bgA.addChild( tgA );
bgB.addChild( tgA);
The last line will throw the exception you've indicated.
