Thank you Eric, much appreciated. I have things up and running now.

A couple additional things I don't understand how to do with my example:

How do I capture the node that the user clicks? I will need to grab
that information to make my database call.

Also, for each item in the tree, I want to build a hyperlink with
parameters. What is the best way to go about this?

I have looked everywhere for examples of a tree like this. Since I'm
not used to javascript (out of my J2EE comfort zone), I rely on a good
example, but havent' had any luck finding one)

Thanks again!
