Help. I need a Tree

[Frank Carver]

I'm writing a general purpose HTML/javascript "tree" component, and I really need a data model to put behind it. The nearest thing I can find is javax.swing.TreeModel, which seems to be mostly what I want, but I don't use swing (or AWT) anywhere else in my application, and I'm loath to start importing it now.
Why is there no java.util.Tree interface like there is for Map, Set and List? Am I missing something, or is there a gaping hole in the standard APIs? How does everyone else deal with this?

Hi,
What about
java.util.TreeSet, and
java.util.TreeMap?
Manfred.

Frank:
while searching for applet limitations, I stumbled on
this FAQ, which IMHO, is related to what you want.
You might want to take a peak at what they are talking...

                               There's a server side JavaBean called
                               CSTreeBean that allows you to populate a
                               tree from a Jdbc data source (a flat
                               de-normalised table) containing node-labels
                               and corresponding URLs, and render the
                               tree as HTML. It's at
                               <A HREF="http://www.coolservlets.com" TARGET=_blank rel="nofollow">www.coolservlets.com</A>  It's very
                               straightforward to use, and maintains tree
                               state either through the URL or the
                               session. There are some limitations and it's
                               still in development, but it works and can
                               handle hundreds (thousands) of tree
                               nodes.
