Loading OBJ-File BY COPY ?

Question

Hello!
I want to load a 3D-Model in OBJ-Format in my Scene with the standard Objectloader com.sun.j3d.loaders.objectfile. This works basically well.
But I need to get hold of the Vertices of the Model and their colors. And this is the Problem:
-I try to get the Coordinates from the Shape3Ds GeometryArray with getCoordinate() and receive the following error:
GeometryArray: cannot directly access data in BY_REFERENCE mode
This is as I assume because the loader creates the Shape3D BY REFERENCE.
Is there another loader or a trick, so that the GeometryArrays of my loaded OBJ-Models are set up as BY COPY?
Code where I load my Model:
public BranchGroup UseOBJModel_Old(String path)
        ObjectFile loader = new ObjectFile();
        BranchGroup bg = new BranchGroup();
        Shape3D shape = new Shape3D();
        try
            Scene tmpScene = loader.load(path);
             Enumeration children = tmpScene.getSceneGroup().getAllChildren();
            //Combining all Shape3Ds from the OBJ-Model into one single shape
            while(children.hasMoreElements())
                 Shape3D tmp = (Shape3D)children.nextElement();
                 shape.addGeometry(tmp.getGeometry());      
            //TODO: Hard setting of Color for OBJ-Shape.Can be improved later
            Appearance objApp = new Appearance();
            Material objMat = new Material();
            ColoringAttributes col = new ColoringAttributes();
            objMat.setAmbientColor(new Color3f(.3f,.3f,.3f));
            objMat.setDiffuseColor(new Color3f(.5f,.5f,.5f));
            objMat.setSpecularColor(new Color3f(.6f,.6f,.6f));
            objMat.setLightingEnable(true);
            objApp.setMaterial(objMat);
            objApp.setColoringAttributes(col);
            col.setColor(.6f,.6f,.6f);
            shape.setAppearance(objApp);
            bg.addChild(shape);
            return bg;
        }Code where the Error occurs:
for(int j = 0; j < originalArray.getValidVertexCount() / divisor; j++)//Calculate Points for LOD-Models
            for(int k = 0; k < divisor; k++ )
               // This tells me that the Array is NOT in BY REFERENCE-Mode. Funny thing
                System.out.println("By-Reference-Status: " + originalArray.getCapability(GeometryArray.BY_REFERENCE));
               originalArray.getColor(index,col[k]);//Here's the Error
               originalArray.getCoordinate(index++,pos[k]);//And here,too
        }Hope I could make it clear what my Problem is, as this is my first post here...
Bye

D'Oh!
First post, and already posted the wrong code...
This is the right code, where I load the OBJ-Model:
public void UseOBJModel(String path)
        ObjectFile loader = new ObjectFile();
        Shape3D shape = new Shape3D();
        try
            Scene tmpScene = loader.load(path);
             Enumeration children = tmpScene.getSceneGroup().getAllChildren();
             Shape3D tmp = (Shape3D)children.nextElement();
             shape.setGeometry(tmp.getGeometry(),0);//This for killing the leading null in the GeometryList
            //Combining all Shape3Ds from the OBJ-Model into one single shape
            while(children.hasMoreElements())
                tmp = (Shape3D)children.nextElement();
                 shape.addGeometry(tmp.getGeometry());      
            //TODO: Hard setting of Color for OBJ-Shape.Can be improved later
            Appearance objApp = new Appearance();
            Material objMat = new Material();
            ColoringAttributes col = new ColoringAttributes();
            objMat.setAmbientColor(new Color3f(.3f,.3f,.3f));
            objMat.setDiffuseColor(new Color3f(.5f,.5f,.5f));
            objMat.setSpecularColor(new Color3f(.6f,.6f,.6f));
            objMat.setLightingEnable(true);
            objApp.setMaterial(objMat);
            objApp.setColoringAttributes(col);
            col.setColor(.6f,.6f,.6f);
            shape.setAppearance(objApp);
            SetOriginalShape(shape);
        catch(FileNotFoundException e)
            System.err.println("Something went wrong while loading OBJ-File");
    }Sorry...
