Center JLabels in component

Question

Hi friends!
I have a problem in disposing some JLabels in a JPanel.
I'm using the BoxLayout to have a JLabel "per line".
  setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));I want to center the labels in horizontal and vertical axis.
To center horizontal I use
jLabel.setAlignmentX(CENTER_ALIGNMENT);I want to center in vertical axis so I wrote
jLabel.setAlignmentY(CENTER_ALIGNMENT);but this doesn't work!
Does anyone know what's the problem??
Please help!
Thanks in advance.

I try to do your suggestions but it doesn�t work.
Here http://webx.ubi.pt/~a13933 I show a screenshot of my application, as you can see the labes are in the top of cells. I want to center them. I'm doing this at the cellRender.
here is the code.
public class JLabelCellRender extends JLabelsPanel implements  TableCellRenderer {
    Border b;
    /** Creates a new instance of PLIconLabel */
    public JLabelCellRender() {
        super(); /* null indicates no layour manager */
        setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
        b=BorderFactory.createLineBorder(Color.black);
    public java.awt.Component getTableCellRendererComponent(JTable table,
            Object value,
            boolean isSelected,
            boolean hasFocus,
            int row, int column) {
        removeAll();
        setBackground(getCor());
        Vector modulos=(Vector)value;
          JLabelModuloTurmaMouseEvents me=new JLabelModuloTurmaMouseEvents();
        if(modulos.size()==0)
            return this;
        for(int i=0;i<modulos.size();i++){
            JLabelModuloTurma x=(JLabelModuloTurma)modulos.elementAt(i);
            x.addMouseListener(me);
            x.setAlignmentX(CENTER_ALIGNMENT);
            x.setAlignmentY(BOTTOM_ALIGNMENT);
            if(!x.getText().equals(""))
            x.setBorder(b);
            add(x);
        return this;
}Please help. Thanks again.
