scrollable jpanel

Hi,

I have a swing application using with several jpanel's contained in a jframe I am trying to make it so one of the jpanels is vertically scrollable. I have tried to use a jscrollpane to achieve this goal but for some reason all that happens is the size of the jpanel keeps getting bigger. I don't know if I am screwing up the viewport or what. The jpanel itself contains just a large group of jtextpane's and jlabel's. Here is the code that I use to try and implement this scroll feature:

// Initialize components of textPane
    textPane = new JPanel();
    textPane.setLayout(new FlowLayout(FlowLayout.LEADING));
    textPane.setPreferredSize(new Dimension(350, 300));

    question_lbl = new JLabel("Question:");
    correct_lbl = new JLabel("Correct Answer:");
    incorrect_lbl = new JLabel("Incorrect Answer:");

    question_txt = new JTextArea(3,65);
    question_txt.setBorder(BorderFactory.createLoweredBevelBorder());
    question_txt.setLineWrap(true);
    question_txt.setWrapStyleWord(true);

    correct_txt = new JTextArea(3,65);
    correct_txt.setBorder(BorderFactory.createLoweredBevelBorder());
    correct_txt.setLineWrap(true);
    correct_txt.setWrapStyleWord(true);

    incorrect_txt = new JTextArea(3,65);
    incorrect_txt.setBorder(BorderFactory.createLoweredBevelBorder());
    incorrect_txt.setLineWrap(true);
    incorrect_txt.setWrapStyleWord(true);

    //add components to textPane
    textPane.add(question_lbl);
    textPane.add(question_txt);
    textPane.add(correct_lbl);
    textPane.add(correct_txt);
    textPane.add(incorrect_lbl);
    textPane.add(incorrect_txt);

    scrollPane = new JScrollPane(textPane);
    scrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);  

Then of course I add scrollPane to the contentPane at a later time. Any suggestions or help would be most appreciated.

Thanks
