How to Use different icons for JTree in the same level

Question

Hi guys, i come cross a problem with JTree. The module need a JTree which need to represent items in the same level using different icons. For example:
[Icon for Root]Root
|
|_____________[Icon for Table] TABLES
|
|_____________[Icon for Index] INDEXS
|
|_____________[Icon for Views] VIEWS
As i know, the default behavior for JTree is using the same icon for all leaves and
the same icon for all node that has children. How can i achieve that?
Thansk a lot!

subclass DefaultTreeCellRenderer. if you overwrite the method below, then you can set the icon to whatever you want....!
    public Component getTreeCellRendererComponent(JTree tree, Object value,
                                boolean sel,
                                boolean expanded,
                                boolean leaf, int row,
                                boolean hasFocus) {
     String         stringValue = tree.convertValueToText(value, sel,
                           expanded, leaf, row, hasFocus);
        this.tree = tree;
     this.hasFocus = hasFocus;
     setText(stringValue);
     if(sel)
         setForeground(getTextSelectionColor());
     else
         setForeground(getTextNonSelectionColor());
     // There needs to be a way to specify disabled icons.
     if (!tree.isEnabled()) {
         setEnabled(false);
         if (leaf) {
          setDisabledIcon(getLeafIcon());
         } else if (expanded) {
          setDisabledIcon(getOpenIcon());
         } else {
          setDisabledIcon(getClosedIcon());
     else {
         setEnabled(true);
         if (leaf) {
          setIcon(getLeafIcon());
         } else if (expanded) {
          setIcon(getOpenIcon());
         } else {
          setIcon(getClosedIcon());
        setComponentOrientation(tree.getComponentOrientation());
     selected = sel;
     return this;
    }
