JScrollPane problem
I've tried to display a JPanel (bigger than screen) with a JScrollPane.
Arbore w =new Arbore(root);//this class extends JPanel
JFrame jf =new JFrame();
JScrollPane jsp =new JScrollPane();
JPanel jp =new JPanel();
jp.setLayout(new BorderLayout());
jf.getContentPane().add(jp);
jsp.getViewport().add(w);
jp.add(jsp,BorderLayout.CENTER);
jf.setExtendedState(JFrame.MAXIMIZED_BOTH);
jf.setVisible(true);
jf.setDefaultCloseOperation(jf.EXIT_ON_CLOSE);
The aplication runs, but I have no scrolls. Why?

Scrollbars will appear automatically when the preferred size of the component is greater than the size of the scroll pane.
I'm guessing you are using a null layout manager and haven't set the preferred size correctly.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program[/url] (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags[/url] so the posted code retains its original formatting.
