Hello Catherine,
In my project I use Jess in the same way. I defclass a bunch of Java objects
and create definstance facts with them. I don't know of a more efficient way
than the one you described. For accessing the Vector you'll have to create a
method getKnowledge in your class ObjectRE (public Vector getKnowledge()
{return knowledge;}). You can call this function in Jess (bind ?k (call ?obj
getKnowledge)) and voil�!
Bye,
Sander
