If you are not required to use Apple s look and feel  a simple fix is to put the following code in your application or applet  before you add any GUI components to your JFrame or JApplet    try       UIManager setLookAndFeel  UIManager getCrossPlatformLookAndFeelClassName         catch  Exception e                e printStackTrace         That will set the look and feel to the cross-platform look and feel  and the setBackground   method will then work to change a JButton s background color
