Custom file chooser

Question

Hello,
I need to design a custom file chooser. Infact, I cannot call it a file
chooser, because this is not accessing local system files. I am uploading
some files into a directory using ASP and I keep that file name in the database.
I can even upload directores and directores with files too into the database.
I need to display those files and folders in the "what is called as file chooser".
The List should work as it works in file chooser. i.e when I click on a folder,
it should show the files inside it. When I click on the file, the file should
be selected. Infact there is nothing in the file. Its all virtual only. Its only
the name that is selected.
I should be given an option to select "directories only" also.
The "file chooser" should not have show files of type, just the file name
text field only. The combobox should display "user added" string message. And
this is only one item in the combobox. I should be able to create folders, show
lists,etc... as it appears in the file chooser. (buttons beside the combobox)
Any ideas would be greatly appreciated.
Thanks

ok, this is just an example....you'll probably need a different constructor and additional methods....
public class VirtualFile{
  private String file ;
  private VirtualFile[] children;
  private VirtualFile parent;
  public VirtualFile(String file,VirtualFile parent,VirtualFiles[]children){
     this.file = file;
     this.parent = parent;
     this.children = children;
  public boolean isRoot(){
    return parent == null;
  public boolean isDirectory(){
    return children = null || children.length==0;
  public VirtualFile[] getChildren){
    return children;
}
