Open source web directory software needed.

I would like to find a java based web directory that I can run on my site.

Ok, given all of those words, I have had no luck at all searching any site to find what I am looking for. As to not cause any confusion, let me explain.

I would like to launch a new web site. This new web site would be hosted on my servers and be a WIDGETS web directory. Think DMOZ, but mine will be all about WIDGETS. A full blow widget directory.
Does any know of an open source Java application that will run a directory site? If not Java, I could settle with php or the like.

If you don't know of one, what other words or phrases could I use when searching. "java web directory software" just brings up page that are about java software.

Thanks!

I host my own directory, I do not use java, php or asp
I use plain html, currently my directory index is PR5 all other pages of my site are PR4, so every single outgoing link that I have on my site will show as a PR4 for them.

I use w3.org's link validator tool once a week to make sure all of my links are valid. I use a form for submissions of new urls or they can be submitted by email.
