I am fairly new to Java 2, and totally new to JFC/Swing.
I cannot get the JScrollPane to appear.  I have consulted
tutorials and samples/demos, and I still can't get it!
All I want is plain scroll bars for plain text - no HTML
or RTF or graphics.  Code follows:

  Color textBoxForegroundColor = new Color(255, 255, 255);
  Color textBoxBackgroundColor = new Color(0, 0, 0);

  JTextArea textBox = new JTextArea();

  JScrollPane scrollPane = new JScrollPane(textBox,
                               JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
                               JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
    scrollPane.setPreferredSize(new Dimension(610, 285));
    scrollPane.setVisible(true);

    textBox.setForeground(textBoxForegroundColor);
    textBox.setBackground(textBoxBackgroundColor);
    textBox.setEditable(false);
    textBox.setFont(new Font("SansSerif", Font.PLAIN, 14));
    textBox.setBounds(8, 90, 610, 285);
    textBox.setVisible(true);

    mainFrame.getContentPane().add(textBox);
