Thank you so very much. With the defclass as you suggested, it
works.
Thank you, thank you, thank you.
P.s. Please disregard another message that I sent out with regard
to this same problem.

You didn't include "personClassificationRules_02.clp" in your
download, but I suspect what's going on is that there's a bad
deftemplate in there, explicit or implicit, which is preventing Jess
from properly associating the PersonDAO class in your package with
an
existing PersonDAO template. Using an explicit
(defclass PersonDAO aoPersistence.PersonDAO)
executed *before* the rules are defined might fix this.
