I wonder if anyone has used the [Jenkov JSP Tree Tag] source code in any of his/her projects. I recently found it and I need any examples on how to use it.

I know there is an exmaple on the product web page, yet I need more so I can use it efficiently.

The product web url is:
http://www.jenkov.dk/projects/treetag/treetag.jsp

and the example url is:
