Problem with adding a Label to a Button

[Anonymous]

Hi,
I need some help with this small code:

    JLabel n = new JLabel( "New" );
    n.setForeground( Color.blue );
    n.setFont( new Font( n.getFont().getName(), Font.BOLD, 20 ) );
    JButton newB = new JButton();
    newB.add( n );
    sidePanel.add( newB ); // this is a JPanel

somethink is strange with this code since it worked with the jsdk 1.3 but I tryed it with jsdk 1.4 and a get the following runtime error:

Well, here is how I would do it:

JButton newB = new JButton("New");
newB.setForeground(Color.blue);
newB.setFont(new Font(newB.getFont().getName(), Font.BOLD, 20));
sidePanel.add(newB);
