[rules-users] Using Hashmap in drl files......

[Nikhil_dev]

Below is the drl file

package com.vtech.ruleengine.module.rulemanagermodule
import com.vtech.ruleengine.module.rulemanagermodule.RuleAttributes;
import java.util.Map;
rule  "Rule_dec_1"
dialect "mvel"
when 
         $a : RuleAttributes()  
         m :  RuleAttributes ( eval( ($a.getValues().get("AdultFare") -
$a.getValues().get("InfantFare")) < ($a.getValues().get("ChildFare") +
$a.getValues().get("InfantFare") ) ) 
then 
         eval($a.getValues().put("GrossFare", 500))
end


Follwing is the way i am using drrols 

                final StatefulSession ruleStateSession =
ruleBase.newStatefulSession();
	        
	        ruleStateSession.addEventListener( new DebugAgendaEventListener()
);
	        ruleStateSession.addEventListener( new
DebugWorkingMemoryEventListener() );

                RuleAttributes objRuleattri = new
RuleAttributes((HashMap<String, Object>)_hmListBean);

	        ruleStateSession.insert(objRuleattri);
	                        
	        ruleStateSession.fireAllRules();

Note : RuleAttributes is a class where i set getter and setter for hashmap

Below is the error message that i get :

[9,0]: unknown:9:0 mismatched token: [@122,385:388='then',<61>,9:0];
expecting type RIGHT_PAREN
ERROR 1 ::getCause::: null
ERROR 2 ::getLocalizedMessage::: Unable to compile drl
ERROR 3 ::getMessage::: Unable to compile drl
ERROR 4 ::toString::: java.lang.RuntimeException: Unable to compile drl
Gross VAlue ::::: 0
java.lang.RuntimeException: Unable to compile drl

It will be very helpful is anyone of you rectify my mistake or tell me any
other way to use Hashmap in drl file.
I am using hashmap, since variable in my application varies hence cannot
define fixed Bean structure.
