For your second question it is not possible to display the POLYGON_FILL and
POLYGON_LINE at the same time. But if you are really aggressive than there can be some
tricks to do it?

Firas,
Two intriguing things about your DirectionalLight code:
1) You don't set a color for the light. Sun's API doc doesn't state
what the default color of the light is but we can assume from the
documentation for the Light class that the default is (1,1,1) (bright
white).
2) You don't set a direction for the light so you'll get the default of
straight down. Thus if you make rectangular objects, and don't tilt
them at all, only the tops (which you probably aren't looking at) are
going to be influenced by the light.
3) Depending on how you are "coloring" your objects they may or may not
react with light. (Suggestion: apply a material to the appearance).
