JavaDB/Derby: Worthy to Have a Try!

Originally, I was looking for an embedded Java database. JavaDB could work in an embedded style, but with 2M limitation. That's terrible. However, since I can control JavaDB server within my Java application, I run the server with a random server port, then connect to it within the same program. Now, my database looks like an embedded one but with no limitation on size. Additionally, JavaDB is much more faster than SQLite3.
