Go to your application folder (if you use NetBeans it will on your NetBeans Project folder), you will find a folder with your database name there. Delete it.

Hope this helps.

Are you running JavaDB as a service? If yes, you have to shut it down before you can delete the db folders.

java -jar derbynet.jar shutdown
