That's one of the aspects of the Derby test harness I dislike, the fact 
that running on a new virtual machine is not obvious. The community is 
moving (slowly) to JUnit so that running the tests becomes more obvious.

There are a number of JUnit test suites that should run standalone 
today. See http://wiki.apache.org/db-derby/DerbyJUnitTesting and 

E.g. try running the test


as a standard Junit test.
