Jess can only pattern-match on Java Bean properties, which are pairs
of getX()/setX() member functions. It can't match on member
variables. Furthermore, it can't directly match the contents of a
Vector, although you could use function calls to extract and compare
the contents of a Vector. Do read the parts of the manual regarding
Java Beans to see what's possible, and look at the jess/examples/pumps
example.
