Answer 1

Swing windows (JFrame, JDialog ...) and internal frames use a "content pane" to hold child components. So you need to set the background of the content pane:

internalFrame.getContentPane().setBackground( Color.RED );

Read the section from the Swing tutorial on Top Level Container for more information.

Keep a link to the Swing tutorial handy for all the Swing basics.

Answer 2

try calling setOpaque(true) on the JInternalFrame
