We don't ship the examples in the package jess/examples anymore; the
small number of examples gave users a distorted view of what's
important about Jess, and as a result most Jess code I saw would be
based on these really inappropriate trivial examples. The mention that
you found in the manual is an error that will now be removed.
In any case, I'll paste the file here so you can see it; it's also
still available in the Jess 6.1 distro. It's very simple. It just
shows Jess calling "store" and Java calling "fetch" -- nothing earth
shattering.

// Send initial parameters to Jess
rete.store("A", new Value(1, RU.INTEGER));
rete.store("B", new Value(3.14159, RU.FLOAT));
rete.store("C", new Point(10,10));
// *************************************************************

" (input-2 ?b)" +
" (input-3 ?c&:(external-addressp ?c))" +

" (store RESULT (+ ?a ?b)))");
// *************************************************************
// Run the rules
rete.reset();
rete.run();
// *************************************************************
// Fetch the result (4.14159) and print it out
System.out.println("The answer is: " + rete.fetch("RESULT"));

re.printStackTrace();
