using - picktool

Hello,

I wanted to pick an Object, f.e.:a Cube in the screen with a pickray object.

My Code is:

PickTool picker=new PickTool(group);

picker.setShapeRay(new Point3d(0.0,-2.0,0.0), new Vector3d(0.0,2.0,0.0));

PickResult result=picker.pickClosest();

but the Result object i get is equal to null (result=null)

i dont know why?

please help, if somebody can..

thanks
