Freeware application that shows a visual schema of a JavaDB (Derby) database

I have created a JavaDB(Derby) database using Netbeans 7.1 on my mac and I am searching for a freeware application that I can use to see a picture of the full database schema with all the tables and their connections. Any ideas? Thank you!
