Yes, the problem is that your code fails to set a renderer to do that actual drawing. Your MyMapFrame constructor is implicitly calling the no-arg constructor of JMapFrame so both the renderer and the map context will be null at that stage. Later you set the map context but never set the renderer.
Try adding this to your MyMapFrame constructor... setRenderer(new StreamingRenderer()); Hope this helps.
