jscrollpane problem

[monkey04]

Hey, I'm having trouble getting scrolling to work properly with a jtextarea. Any help would be appreciated. What I have is basically:

Code:

JTextArea test = new JTextArea();
for (int i = 0; i < 50; ++i) {
    test.append(i + "\tstrings!!! \n");
}
test.setPreferredSize(new Dimension(200, 200));
JScrollPane testScroller = new JScrollPane(test);
testScroller.setVerticalScrollBar(new JScrollBar());
testScroller.setPreferredSize(test.getPreferredSize());
mainPanel.add(testScroller);

This doesn't work right, it only lets me scroll the first 13 or so lines, if at all. How can I set it to work right and handle all the lines of text that may appear??
Thanks!

Code:

        JTextArea test = new JTextArea();
        for (int i = 0; i < 50; ++i) {
            test.append(i + "\tstrings!!! \n");
        }
//        test.setPreferredSize(new Dimension(200, 200));
        JScrollPane testScroller = new JScrollPane(test);
        testScroller.setPreferredSize(new Dimension(200, 200));
//        testScroller.setVerticalScrollBar(new JScrollBar());
//        testScroller.setPreferredSize(test.getPreferredSize());
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setLayout(new GridBagLayout());
        f.add(testScroller, new GridBagConstraints());
        f.setSize(400,400);
        f.setLocation(200,200);
        f.setVisible(true);
