Re: [rules-users] Date arithmetic in âwhenâ session
Ok, finally I am able to solve this puzzle:
$req : LowFareRequest(
$reqTime : requestedDeparture.time)
$itr : AirItinerary( discarded == false )
$flight : Flight( $depart : departure.time)
eval (((Long)$depart).longValue() * 2 <
((Long)$reqTime).longValue() && ((Long)$depart).longValue() * 4 >
((Long)$reqTime).longValue())
Thank you all who helped out.

Hi,
you shouldn't put part of the "if" or "when" part after the
"then". Put
all conditions after the "when" so the rule engine will evaluate them.
I guess you mean to write something like (although I haven't tested this):
rule "ITR Discard"
when
req : LowFareRequest(
$reqTime : requestedDeparture.time)
itr : AirItinerary( discarded == false )
flight : Flight(
departure.time - 2 * 3600000 <
$reqTime,
departure.time + 4 * 3600000 >
$reqTime)
then
System.out.println("discard true");
end
