You have to convert the 2d screen coordinate into a 3d world space coordinate and move the object to that position. For example by using this method: http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Interact2D.html#reproject2D3DWS(com.threed.jpct.Camera, com.threed.jpct.FrameBuffer, int, int, float).

Keep in mind that a conversion from 2d to 3d requires one fixed coordinate in 3d, which is usually z. That's why the method takes a z coordinate in 3d in addition to the screen coordinates.
