public void paintComponent (Graphics g) {
g.drawImage(image, 0, 0, this);
super.paintComponent(g);

};
sPan = new JScrollPane(textP);
frame.getContentPane().add(sPan);

frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
frame.setSize(230, 160);
frame.setVisible(true);
}

public static void main(String[] args) {
new Test();
}
}
