救命啊！！！怎样让鼠标点击JTree上的Node时成为手形？

Question

jTree1.addTreeSelectionListener(new TreeSelectionListener() {
            public synchronized void treeWillCollapse(TreeExpansionEvent event)
            {              
            }
            public synchronized void treeWillExpand(TreeExpansionEvent event) {            }
            public void valueChanged(TreeSelectionEvent e)
            {
              setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
            }
        });
