JFrame frame = new JFrame(500,500);

JPanel panel = new JPanel();
pane.setLayout(null);

JTextArea textarea = new JTextArea();

JScrollPane scrollpane = new JScrollPane();
scrollpane.setViewportView(textarea);

frame.add(panel);
panel.add(scrollpane);

scrollpane.setBounds(200,200,30,100);

My goal is to add a scrollpane to the textarea but it wont appear....any tips?
