This is the first time that an entire, production quality Java stack with tooling is being included in an open source GNU/Linux distribution - greatly simplifying the process for Linux developers and users to access Java technology.
You can also check Tom Marble's blog entry for additional information. This is very exciting indeed.
You can 'apt-get' install Java DB as an optional Ubuntu package such as:
# apt-get install sun-java6-javadb
and it should get installed under '/usr/lib/jvm/java-6-sun/db/'
