Actually, Derby doesn't have an in-memory mode ( http://db.apache.org/derby/faq.html#in_memory), and saves the data to disk by default. The JDBC connection URL determines the directory that Derby saves stuff in. In the ToDo app I believe it's "lift_example", which should be in your project root directory. You can just delete that directory and it wipes the DB.
