Hi John,
The only way to pattern-match Java objects is via Bean properties,
yes. But you can create Java objects, call their methods, access their
variables, etc. at any time by using the appropriate Jess function
calls. See examples/frame.clp, for instance, or examples/draw.clp, or
section 2.6 of the manual ("Java reflection") and the other sections
referenced therein.
You can use all of this stuff on both the RHS and LHS of rules.
