<DIV>Hi All,</DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV><U><B>Claims.drl </B></U></DIV>

<DIV> </DIV>
<DIV>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. </DIV>
<DIV>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?</DIV>
<DIV> </DIV>
<DIV>Thanks, </DIV>
