Button.requestFocus(); does not give the focus to a button...

Question

I have a Frame with a message (textPane) and a button, for accept the message. I want the button to be focused when I open the frame, so this will allow the user to just press one key for accepting the message without use the mouse.
How can I acomplish this???!!!
Thanks on advance.

I still cannot give the focus to the button when I open the JDialog.
My code is this:
public class VError extends JDialog
GridBagLayout gridBagLayout1 = new GridBagLayout();
JTextPane jTextPane1 = new JTextPane();
JPanel jPanel1 = new JPanel();
JButton jButton1 = new JButton();
GridBagLayout gridBagLayout2 = new GridBagLayout();
String message;
ResourceBundle mes = ResourceBundle.getBundle("com.saincotrafico.optimus.client.resources.RError",Locale.getDefault());
MutableAttributeSet mas;
public VError(String message)
this.setSize(250,150);
this.setResizable(false);
this.getContentPane().setBackground(UIManager.getColor("Panel.background"));
this.setTitle(mes.getString("title"));
this.message = message;
try
jbInit();
catch(Exception e) {
e.printStackTrace();
private void jbInit() throws Exception
mas=new SimpleAttributeSet();
StyleConstants.setAlignment(mas,StyleConstants.ALIGN_CENTER);
jTextPane1.setParagraphAttributes(mas,true);
jTextPane1.setEditable(false);
jTextPane1.setSelectedTextColor(Color.black);
jTextPane1.setText("\n"+message);
jTextPane1.setBackground(this.getBackground());
jTextPane1.setEditable(false);
this.getContentPane().setLayout(gridBagLayout1);
jButton1.setSelected(true);
jButton1.setText(mes.getString("aceptar"));
jButton1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
jButton1_actionPerformed(e);
jPanel1.setLayout(gridBagLayout2);
this.getContentPane().add(jTextPane1, new GridBagConstraints(0, 0, 1, 1, 0.0, 1.0
,GridBagConstraints.CENTER, GridBagConstraints.BOTH, new Insets(0, 0, 0, 0), 0, 0));
this.getContentPane().add(jPanel1, new GridBagConstraints(0, 1, 1, 1, 1.0, 0.0
,GridBagConstraints.SOUTH, GridBagConstraints.HORIZONTAL, new Insets(0, 0, 10, 0), 0, 0));
jPanel1.add(jButton1, new GridBagConstraints(0, 0, 1, 1, 0.0, 0.0
,GridBagConstraints.NORTH, GridBagConstraints.NONE, new Insets(5, 157, 5, 158), 0, 0));
this.getRootPane().setDefaultButton(jButton1);
jButton1.requestDefaultFocus();
jButton1.requestFocus();
void jButton1_actionPerformed(ActionEvent e)
this.dispose();
}
