Hi All,

I have small doubt in the DRL file execution. I have developing the small Claims application. I have 4 rules in my application. Below are the rules I have declared in the drl file based on the rules.

Claims.drl

rule "Amount Validation-Rule1"

when

$c : Claims(amount >= ( maxClaimAmount) )

then

$c.setMessage ( "The total amount claimed exceeds the maximum permitted by the

Policy" );

update($c);

end

rule "Expired Policy-Rule2"

when

$c : Claims( currentDate > ( policyExpireDate ))

then

$c.setMessage( "Your Policy has been expired" );

update($c);

end

rule "Feature Date-Rule3"

when

$c : Claims( claimDate >= ( currentDate ) )

then

$c.setMessage( "Rejecting the claim because the date on the claim is in the future" );

update($c);

end

and my java class is

Claims.java

// Setting the values to Claims object

Claims rule = new Claims ();

rule.setAmount(amount);

rule.setClaimsHospitalStayeddays(claimsHospitalStayeddays);

rule.setClaimDate(claimDate);

rule.setCurrentDate(currentDate);

rule.setDaysPermitted(daysPermitted);

rule.setPolicyExpireDate(policyExpireDate);

rule.setCurrentDate(currentDate);

rule.setMaxClaimAmount(maxClaimAmount);

StatefulSession workingMemory = ruleBase.newStatefulSession();

workingMemory.insert(rule);

workingMemory.fireAllRules();

If my first rule is fails then it is displaining in the messaege I managed to get that value in my java class. If the condition is not satisfied then is fell into the infinte loop. Again and again it is calling, not coming from that loop. If I keep the drools.halt(); at the end of the rule then it is executing.

My question – Is there any alternate method is there to come out from infinte loop without using drools.halt(); method? Why it is fell into the infinite loop?

Thanks,
