Hi ,
I've below rule set up in Guvnor . This rule works fine when other java
application starts up and fetched the rule from Guvnor using knowledge Agent
.
rule "EL-AH-RESTRICT-LOGIN"
no-loop true
dialect "mvel"
when
lcki : LoginChallengeKI( eval( (lcki.getWS_RiskScore() >=
790 && (lcki.getWS_RiskScore() - lcki.getAvgRiskScore()) >= 500) ||
(lcki.getWS_RiskScore() >= 750 && ((lcki.getWS_RiskScore() -
lcki.getWS_RiskScore())/lcki.getWS_RiskScore()) >= 4) ||
(lcki.getWS_RiskScore() >= 750 && lcki.getWS_RiskScore() <= 350 ) ),
userEquityBalance >= 40 , hadPreviousChallenge == false , eval(
!lcki.getValidCookies().contains(lcki.getWS_Cookie()) &&
!lcki.getValidCookies().contains(lcki.getWS_FlashCookie()) ), eval(
lcki.getWS_IPAddr() != lcki.getIpAddr1() && lcki.getWS_IPAddr() !=
lcki.getIpAddr2() ), eval( lcki.getWS_Cookie() != lcki.getCookie1() &&
lcki.getWS_Cookie() != lcki.getCookie2() ), eval( lcki.getWS_FlashCookie()
!= lcki.getFlashCookie1() && lcki.getWS_FlashCookie() !=
lcki.getFlashCookie2() ), eval( lcki.getWS_GeoCity() != lcki.getGeoCity1()
&& lcki.getWS_GeoCity() != lcki.getGeoCity2() ), eval(
CheckAfterHour(lcki.WS_EventTimeStamp) ))
then
lcki.setRuleIDMapValue("ACT03","EL-AH-RESTRICT-LOGIN");
lcki.setChallenge(true);
lcki.setGenerateAlert(true);
end
But if i make any change in the in the guvnor and build the pkg then other
application throws below exception
org.drools.RuntimeDroolsException: Exception executing predicate
(lcki.getWS_RiskScore() >= 790 && (lcki.getWS_RiskScore() -
lcki.getAvgRiskScore()) >= 500) || (lcki.getWS_RiskScore() >= 750 &&
((lcki.getWS_RiskScore() - lcki.getWS_RiskScore())/lcki.getWS_RiskScore())
>= 4) || (lcki.getWS_RiskScore() >= 750 && lcki.getWS_RiskScore() <= 350 )
