Reloading a JTree from a saved file

Question

I read a JTree from a file. I want to show it in my JPanel. I reload the DefaultTreeModel after reading the file but, it doesn't work.

public class DynamicTree extends JPanel 
{
    protected   myDefaultMutableTreeNode rootNode;
    protected   DefaultTreeModel treeModel;
    protected   JTree tree;
    private transient  Toolkit toolkit = Toolkit.getDefaultToolkit();
    private      URL helpURL;

    public void reloadModel(){this.treeModel.reload();}
}

Read the file for loading DynamicTree

address = (DynamicTree) ReadDynamicTreeFromFile();

 MainPanel.SetTree4load(address);

The SetTree4load(address) method is:

 public static void SetTree4load(DynamicTree tree)
    {
         treePanel=tree;       //treepanel is the current DynamicTree in the frame
         treePanel.reloadModel();
    }

Thanks in advance :)

Instead of changing the tree. Try to set the model and the datamodel from the loaded tree to the panel tree
