Hello, I'm writting an expert system in jess. It includes the two kinds of
templates, the ones that you can define from java (using declare from-class)
and the ones that you define directly in the clp archive. The beans are all
of the same kind, all of the contains Strings.
I've experimenting some problems when I want to execute a query that is
defined in the clp archive from java, regarding a template defined a java
bean. When i want to pass a parameter, the rules does not match with any of
the facts. Jess engine had stored the strings of the beans with "". Does
anyone can give me a tip in how to execute a query from java regarding facts
created as java bean objects???
Here is the query that i run from java:
QueryResult result;
try {
result = jessEngine.runQueryStar("llamados", new
ValueVector().add("metodo1"));
while (result.next()) {
System.out.println(result.getString("caller_id") + " " +
result.getString("callee_id")));
addFanInMetric(ff);
}
} catch (JessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Here is the clp archive:
(import JessIntegrationModel.*)
(deftemplate Call (declare (from-class Call)))
(deftemplate llamado_no_directo
"comment"
(slot caller_id)
(slot calle_id))
(deftemplate metodoFamiliar
(slot metodo1)
(slot metodo2)
)
(deftemplate metodoFamiliar_counted
(slot metodo1)
(slot metodo2)
)
(defrule propagarLlamadas
(declare (salience 500))
(Call (callee_id ?metodoLlamado)(caller_id ?metodoLlamador))
(metodoFamiliar (metodo1 ?metodoLlamado)(metodo2 ?metodoFamiliar))
(not (metodoFamiliar_counted(metodo1 ?metodoLlamado)(metodo2
?metodoFamiliar)))
=>
(assert (metodoFamiliar_counted(metodo1 ?metodoLlamado)(metodo2
?metodoFamiliar)))
(assert (llamado_no_directo(calle_id ?metodoFamiliar)(caller_id
?metodoLlamador)))
)
(defquery llamados
"comment"
(declare (variables ?ln))
(call_counted (caller_id ?Caller) (callee_id ?ln))
)
(defquery llamadosNoDirectos
"comment"
(declare (variables ?ln))
(llamado_no_directo (caller_id ?Caller) (calle_id ?ln))
)
