The only way to define a rule is via the Jess language
representation. Jess's public Java API doesn't allow you to create
rules. Maybe someday...

Don't believe everything you read. The script form of a rule is
translated into a Java data structure when it is initially parsed,
then compiled into the Rete network. The time taked to add a rule to
the network is much larger than the time taken to translate the script
form of a rule into a jess.Defrule objects. In other words, even if
you could create Defrule objects yourself in Java, it would have no
performance impact whatsoever.

*** As I said, there's no choice here.
What the earlier poster was talking about was code on rule RHS, or
other procedural code. It is indeed faster to do computations in Java
code and call it from Jess than it is to do the same operations in
Jess's scripting language.
