🚀 go-pugleaf

When I place a JTextArea in a JScrollPane and add succesive lines of
text using add method no scrollbars appear and I can't see lines of
text past the bottom of the frame. Any suggestion on what I am doing
wrong with textarea?

relevant code....
public MyJFrame extends JFrame{

....
  JScrollPane jsp = new JScrollPane();
  JTextArea jta = new JTextArea();
...
   jsp.getViewport().add(jta, null);
   bevelPanel1.setLayout(borderLayout1);
   bevelPanel1.add(jsp, BorderLayout.CENTER);
   this.getContentPane().add(bevelPanel1, BorderLayout.CENTER);
....
  public static void main(String[] args) {
   MyJFrame jf = new MyJFrame();

   for (int i = 1; i < 50; i++)
       jf.jta.addLine("Test: " + Integer.toString(i));

Here I can't scroll to text below line 20 which is the size of the
frame.

Any help would be appreciated...
Thanks
