Using a JTree as an explorer

Question

Hi all of you there!
I made a JTree from my local disk (c:/) en in that JTree I can navigate through al the folders of my C-disk.
Now I want to have the directory of the file that is highlighted. I already try lot of things but no one work.
The best thing I get was: "nodeinfo = [Ljavax.swing.tree.TreeNode;@110c31"
{code}
     private JScrollPane getFileScrollPane(String file) {
if (fileScrollPane == null) {
               fileScrollPane = new JScrollPane();
               fileScrollPane.setPreferredSize(new Dimension(200, 400));
          File root;
          FileTreeModel model;
          //JTree tree;
               root = (new File(file));
     model = (new FileTreeModel(root));
     tree = new JTree();
     tree.setModel(model);
tree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);
tree.addTreeSelectionListener(tree);
               tree.addTreeSelectionListener(new TreeSelectionListener() {
               public void valueChanged(TreeSelectionEvent e) {
                    DefaultMutableTreeNode node = new DefaultMutableTreeNode();
tree.getLastSelectedPathComponent();
                    /* if nothing is selected */
               if (node == null)
                    return;
               /* retrieve the node that was selected */*
               Object nodeInfo = node.getPath();
               //Object nodeInfo = node.getUserObject();
               System.out.println("nodeinfo = " + nodeInfo);
               System.out.println("root=" + node.getParent());
     fileScrollPane = new JScrollPane(tree);
     fileScrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
     fileScrollPane.setPreferredSize(new Dimension(315, 300));
          return fileScrollPane;
     }{code}
the String file contains "c:/"
I hope that someone can help me

Hi, thanks for your help!
But it won't work.
Now I get the following error: (I paste everything in here, maybe someone wants to see it all)
