this is the code i wrote, firstly you should be extending Jlabel and
implementing the tree Renderer interface,


this will work, if you need any help just ask:

public class treeRenderer extends JLabel implements TreeCellRenderer
{
        static protected ImageIcon        Icon1;
    static protected final Color SelectedBackgroundColor =
SystemColor.textHighlight;//new Color(0, 0, 128);



    /** Whether or not the item that was last configured is selected. */
    protected boolean            selected;


 public treeRenderer(){
 try {
     defaultFont = new Font("SansSerif", 0, 12);
 } catch (Exception e) {}
 try {
     Icon1 = new ImageIcon(<name of icon>.gif);

// you can have as many icons as you want

 } catch (Exception e) {
     System.out.println("Couldn't load images: " + e);
 }
    }




      public Component getTreeCellRendererComponent(JTree tree, Object
value,
       boolean selected, boolean expanded,
       boolean leaf, int row,
        boolean hasFocus) {
 Font            font;
 String          stringValue = tree.convertValueToText(value, selected,
        expanded, leaf, row, hasFocus);
  String val =  value.toString();

 /* Set the text. */
 setText(stringValue);
 /* Tooltips used by the tree. */
 setToolTipText(stringValue);
  String t =stringToken(val);
       if(<some thing>)
          setIcon(Icon1);
        else if(<something>)
         ..
        ..

 /* Update the selected flag for the next paint. */
 this.selected = selected;

 return this;
    }
    public void paint(Graphics g) {
 Color            bColor;
 Icon             currentI = getIcon();

 if(selected)
     bColor = SelectedBackgroundColor;
 else if(getParent() != null)

     bColor = getParent().getBackground();
 else
     bColor = getBackground();
 g.setColor(bColor);
 if(currentI != null && getText() != null) {
     int          offset = (currentI.getIconWidth() + getIconTextGap());

     g.fillRect(offset, 0, getWidth() - 1 - offset,
         getHeight() - 1);
 }
 else
     g.fillRect(0, 0, getWidth()-1, getHeight()-1);
 super.paint(g);
    }
}
