It is called Oracle WebDB.

We use it in conjunction with Coldfusion where I work. Works pretty Darn slick.

It comes down to wether or not your DB allows another Listener for the DB. Also depends on how you have it configured. If you configure it to only listen to the local machine... it pretty much ignores anything except localhost (127.0.0.1)

That may be a clue for you. Do you have a "localhost" name in your "hosts" file!!??? If you know where it is that is!!!
