Well, yes. Defining a rule doesn't do anything; you'd have to run the
rule. Then you'd have to have the rule -do- something with the result,
to make it available to you in Java. You could use the store and fetch
functions; see manual section 4.4.4. The rule calls store, and then
you call fetch in Java. If you store ?factID, the Java object you
fetch will be a jess.FactIdValue.

It would be more appropriate, though, to use a defquery instead of a
rule here; see manual section 2.9.
