File Browser with JTree or JPanel

Hallo everybody,

i need urgent to improve my GUI Application that i have made. I want to make a file browser like JFileChooser (all should be listed) but i want to change the view from JFileChooser with my own. And I want that JTree or JPanel to browse files and folders, which one is better ? Any help would be appreciated. For a sample code or simple guide will be accepted.

This java.codefetch.com query for "jtree file" found this code example of how to display a file system in a JTree view from the book Java Cookbook
