Hi, I am using drools version 3.0. I have a recursion problem while executing a rule. Here is the sample code. import com.thirdpillar.QuoteUpdater import java.lang.String import java.math.BigDecimal global BigDecimal TEMP global BigDecimal GL_SD_Amt rule "gst_rate_ol" no-loop true salience 50 when QuoteUpdater:QuoteUpdater() eval(QuoteUpdater.getCustomerTypeCountry().equals("New Zealand") && QuoteUpdater.isFinanceLease() == true || QuoteUpdater.isRental() == true || QuoteUpdater.isOperatingLease() == true || QuoteUpdater.isHirePurchase() == true) then System.out.println("1"); TEMP = BigDecimal . valueOf ( 0.125 ) ; QuoteUpdater . setQuoteLevelGSTRate ( BigDecimal . valueOf ( TEMP . doubleValue ( ) ) ) ; modify(QuoteUpdater); end rule "NZ_SD" no-loop true salience 45 when QuoteUpdater:QuoteUpdater() eval(QuoteUpdater . getCustomerTypeCountry ( ).equals("New Zealand")) then System.out.println("2"); QuoteUpdater . setQuoteLevelGSTStreamRate ( BigDecimal . valueOf ( 0 ) ) ; QuoteUpdater . setQuoteLevelStampDutyRate ( BigDecimal . valueOf ( 0 ) ) ; GL_SD_Amt = BigDecimal . valueOf ( 0 ) ; QuoteUpdater . setQuoteLevelStampDutyAmount ( BigDecimal . valueOf ( 0 ) ) ; modify(QuoteUpdater); end rule "gst_stream_rate_ol" salience 40 no-loop true when QuoteUpdater:QuoteUpdater() eval(QuoteUpdater.getCustomerTypeCountry().equals("New Zealand") && QuoteUpdater.isRental() == true || QuoteUpdater.isOperatingLease() == true) then System.out.println("3"); TEMP = BigDecimal . valueOf ( 0.125 ) ; QuoteUpdater . setQuoteLevelGSTStreamRate ( BigDecimal . valueOf ( TEMP . doubleValue ( ) ) ) ; modify(QuoteUpdater); end Please help me out to resolve this problem. If you have any solution of how to handle it please give your inputs and suggestions. Regards, KAPIL
