Drools Collection Iteration

Question

what's Wrong with this rule.

rule "Organization Employee Rule"
    when

        $company: CompanyFact( $emp: /employeeList{organizationName== "XYZ"})

    then
        System.out.println("Employee in organization" +$emp);
end

I am getting this error while trying to run this rule.

[ERR 102] Line 23:44 mismatched input '{' in rule "Organization Employee Rule"

CompanyFact has list of Employee and Employee has String organization name.

If you are using Drools 7.x, they changed the OOPath syntax to make it closer to XPath.

Try to use square brackets instead of curly ones:

rule "Organization Employee Rule"
when
    $company: CompanyFact( $emp: /employeeList[organizationName== "XYZ"])
then
    System.out.println("Employee in organization" +$emp);
end

Hope it helps,
