JTree: editable node

Question

Hello, I want some help because I have a tree and I want to give the user the possibility to change the selected node value ( to have an editable node with a rightclick).
I used this methods :
setEditable (true) and startEditingAtPath()
But I want to get the new value to change the database and reload the tree. How to do ?
thanks

I think I forgot something, Could you say me If I am right ?
I have a popupmenu "rename" for the tree
RenameMenuItem.addActionListener(new ActionListener()
      public void actionPerformed(ActionEvent e)
        Tree.setEditable();
    }); // RenameMenuItem
[\code]
and I have the setEditable method :public void setEditable() {
TreePath treePath = Arborescence.getSelectionPath();
DefaultTreeModel treeModel = (DefaultTreeModel)myjtree.getModel();
treeModel.addTreeModelListener(new MyTreeModelListener());
myjtree.setEditable(true);
myjtree.startEditingAtPath(treePath);
}//setEditable
[\code]
and mytreemodellistener class
class MyTreeModelListener implements TreeModelListener {
  public void treeNodesChanged(TreeModelEvent e) {
    DefaultMutableTreeNode node;
    DefaultMutableTreeNode nodee;
    TreePath path = e.getTreePath();
    node = (DefaultMutableTreeNode)(path.getLastPathComponent());
    System.out.println("node 1 ="+node);
    nodee = (DefaultMutableTreeNode
    try {
      int index = e.getChildIndices()[0];
      node = (DefaultMutableTreeNode)(node.getChildAt(index));
      System.out.println("node 2 ="+node);
    catch (NullPointerException exc) {
      System.out.println("TreeModelListener :"+exc.getMessage());
    String newNode =  node.toString();
    System.out.println("New value: " +newNode);
  public void treeNodesInserted(TreeModelEvent e) {
  public void treeNodesRemoved(TreeModelEvent e) {
  public void treeStructureChanged(TreeModelEvent e) {
}// MyTreeModelListener
[\code]
The "node 1" printing in the MyTreeModelListener is the father whereas I change the child and the "node 2" is the child then I don't know how can I retrieve the old name of the child in my database to change its label .
thanks a lot !
