Hi,
I like to build a agent solution. Jade with jess.
So I test little thinks first in jess.
I have a problem running the pump example.
java -classpath jess.jar jess.Main jess/examples/pumps/pumps.clp
This is the pump.clp file
;;(defclass machine jess.examples.pumps.Machine )
(deftemplate machine (slot name) (slot class) (slot OBJECT)) (defclass tank
Tank extends machine) (defclass pump Pump extends machine)
I made a test also with:
(defclass pump jess.examples.pumps.Pump )
(defclass tank jess.examples.pumps.Tank )
(deftemplate pump (slot name) (slot class) (slot OBJECT)) (deftemplate tank
(slot name) (slot class) (slot OBJECT)) (defclass tank Tank) (defclass pump
Pump)
There is no machine class in the example
What can I do?
