changing an icon in a button

-----------------------------------

i have this problem with changing the icon in my button...
these is the situation

i am making a chinese chess game. i designed my board using JButton so my board is composed of 90 buttons(pure board without any chess pieces). what i want to do is when i would click a button(new game) i want the board to have the chess pieces...

i tried using setIcon(...) but it didn't work... i could not find the error... when i compiled it there is no error but when i run it and click "new game" something like this would apear in the command prompt

Shouldn't this be in the Java help section?
