[JAVA3D] Extending Canvas3D

[Zak]

I am trying to make my own canvas and extending Canvas3D. This is the code.   public class Globe3DCanvas extends Canvas3D{  public Globe3DCanvas(java.awt.GraphicsConfiguration c){    }  public Canvas3D getCanvas(){   return this;  } }   It is telling me that: Error   : No constructor matching Canvas3D() found in class javax.media.j3d.Canvas3D. Globe3DCanvas.java line 11    public Globe3DCanvas(java.awt.GraphicsConfiguration c)   What is the deal?   Thanks in advance: Zak
