I have defined in Ontology:
private String Mode = "Something";
and
public String getMode(){
return Mode;
But in Jess Editor an error appears in mode: No such slot Mode in
template
MAIN::Ontology at token 'Mode'.
What it is going wrong?
Jess, like Java, is case-sensitive. Jess uses the standard JavaBeans
conventions to derive property names from getter method names, so the
method getMode() gives rise to a property named "mode", all in lower-
case. Therefore just
(defrule testRule1
"Testing the rule."
(Ontology { mode == "Something" })=> ...
should work fine,
