Hello All,
I have an object called Request in java. I am trying to modify the object by
firing a jess rule but i don't find any changes in the object
Request class:
package proto;
import java.io.*;
public class Request implements Serializable
{
public String destination;
public int passengerAge;
public void setDestination(String dest)
{
destination }
public void setPassengerAge(int personAge)
{
passengerAge }
public String getDestination()
{
return destination;
}
public int getPassengerAge()
{
return passengerAge;
}
}
Java code for accessing the jess rules :
final Rete engine
engine.eval("(deftemplate Request (declare
(from-class proto.Request)))");
engine.eval("(deftemplate Proposal (declare
(from-class proto.Proposal)))");
FileReader fp
FileReader("C:\\Users\\Venkat\\workspace\\nnayuni_contract-net_p5\\src\\SellerRules.clp");
final Context context
final Jesp parser
Object result
while(!result.equals(Funcall.EOF))
{
try
{
result
System.out.println(result);
}
catch (JessException e)
{
e.printStackTrace();
}
}
try
{
Request req
Proposal temp
Fact f f.setSlotValue("passengerAge",
new Value(req.getPassengerAge()));
f.setSlotValue("destination",
new Value(req.getDestination()));
engine.assertFact(f);
engine.reset();
engine.run();
System.out.println(req.getPassengerAge());
}
catch (JessException e)
{
e.printStackTrace();
}
catch (UnreadableException e)
{
e.printStackTrace();
}
jess rule :
(defrule welcome-toddlers
"Give a special greeting to young children"
?fact <- (Request {passengerAge > 3})
(modify ?fact (passengerAge 14)))
