Hi All,
I am using Drools 4.0.7 and when I tried to use "matches" operator it is
giving following exception
The rule logic is following
package com.logica.heca.lpr.rule;
import com.logica.heca.lpr.domain.*;
import com.logica.heca.lpr.domain.contact.*;
import com.logica.heca.lpr.domain.ruleengine.*;
import java.util.*;
rule "CPR_RULE_222222"
dialect "mvel"
when
INDUD : ContactVO();
eval(INDUD.districtCode matches "((UX)[ACMR][[A-Z0-9]]{3})|([A-Z0-9]++)")
then
System.out.println("hello");
End
Note: INDUD.districtCode returns String value.
While if I changed matches operator to java method this work fine
eval(INDUD.getDistrictCode().matches("((UX)[ACMR][[A-Z0-9]]{3})|([A-Z0-9]++)"));
any of your esteemed help will highly be appreciated
Thanks
Ravendra Kumar
