Thanks for your help , Sudhir, I used rule when $a:A(b.z.s=="test"); then end And that solved my problem. But I would like to know one more information about global variables. package... dialect java import .., global java.lang.String recipients=&quot;divya(a)gmail.com&quot; global java.lang.String to=&quot;xyz(a)yahoo.com&quot; global java.lang.String cc=&quot;abc(a)gmail.com&quot; rule when when $a:A(b.z.s=="divya"); then $a.setRecipients(recipients); $a.setTo(to); $a.setCC(cc); update($a) end Is this feasible with Drools. I get unable to comile myfile.drl file [9,40]: unknown:9:40 mismatched token: [@49,201:201='=',<71>,9:40]; E exception. Could you please help me with this too.

A couple of more questions, I am calling my rules engine from a service and into the session i am inserting the business object. In my service class, I have a few helper functions, which I need to call from my drl file. How can I do that ?

The problem is that I have a non static function in my service class and i have to call thhat from my drools rule file. The function basically accepts a mail id and if a mailing list returns an arraylist of the individual mail ids in the mailing list. my drl file looks like this: ======================================================== package com.test.ams.rule dialect "java" import java.util.ArrayList; import org.json.JSONArray; import java.net.HttpURLConnection; import java.net.URL; import java.io.InputStream; import java.io.InputStreamReader; import java.io.BufferedReader; import com.test.domobjects.StaffingForm; import com.test.domobjects.StaffingFormOfferDetails; import com.test.domobjects.OfferResponseType; import function com.test.serviceImpl.StaffingFormMailingServiceImpl.expandTheMailingList; global java.util.HashMap myOSFRecipientsMap; rule "Part A" salience 20 no-loop true when $s:StaffingForm(staffingFormOfferDetails.offerValue== true && staffingFormOfferDetails.offerResponseType.offerResponseTypeName == "Accepted") then $s.setPartARecipients((ArrayList<String>)expandTheMailingList((String)myOSFRecipientsMap.get("PART_A_EXEC_COMMITTEE"))); $s.setPartARecipients((String)myOSFRecipientsMap.get("PART_A_CONFIDENTIAL")); $s.setPartARecipients((String)myOSFRecipientsMap.get("PART_A_PAYROLL")); update($s); end ======================================================== This gives me an exception -- java.lang.RuntimeException: Unable to compile "the.drl".

Thanks every one, I found a solution to this. I created an utility class used it in setGlobal of the drools session. Thus, I could call even non static methods from the utility class. Could any one help me with regular expressions in Drools. I want to check the existance of any one of the keywords 'assistant', 'temp', 'intern' in a position field of an object. To be more clear I wanted to get the correct match if these keywords exist as a subword of its own and not as a part of a word. For eg., intern exists in internship and Systems : Intern, here I should get a successful match only for the second one. How can I achieve that ? My sampl drl file looks like: rule "Form the " salience 20 no-loop true when $s:Form(details.position matches "^.*[_-:/](assistant|intern|temp)$"); then $s.setRecipients((ArrayList)utilities.toArrayList((String)myRecipientsMap.get("Recipients"))); update($s); end If would be very helpful if anyone could help me solve this. thanks -D D1vy@@Ind1@ wrote: > > I have still not found a solution to the problem. > > The problem is that I have a non static function in my service class and i > have to call thhat from my drools rule file. > > The function basically accepts a mail id and if a mailing list returns an > arraylist of the individual mail ids in the mailing list. > > my drl file looks like this: > > ======================================================== > package com.test.ams.rule > > dialect "java" > > import java.util.ArrayList; > import org.json.JSONArray; > import java.net.HttpURLConnection; > import java.net.URL; > import java.io.InputStream; > import java.io.InputStreamReader; > import java.io.BufferedReader; > > import com.test.domobjects.StaffingForm; > import com.test.domobjects.StaffingFormOfferDetails; > import com.test.domobjects.OfferResponseType; > import function > com.test.serviceImpl.StaffingFormMailingServiceImpl.expandTheMailingList; > > global java.util.HashMap myOSFRecipientsMap; > > rule "Part A" > salience 20 > no-loop true > when > $s:StaffingForm(staffingFormOfferDetails.offerValue== true && > staffingFormOfferDetails.offerResponseType.offerResponseTypeName == > "Accepted") > then > > $s.setPartARecipients((ArrayList<String>)expandTheMailingList((String)myOSFRecipientsMap.get("PART_A_EXEC_COMMITTEE"))); > > $s.setPartARecipients((String)myOSFRecipientsMap.get("PART_A_CONFIDENTIAL")); > $s.setPartARecipients((String)myOSFRecipientsMap.get("PART_A_PAYROLL")); > update($s); > end > ======================================================== > > > This gives me an exception -- java.lang.RuntimeException: Unable to > compile "the.drl". > > Please let me know what is the problem here. > > > Thanks > -D > > > > D1vy@@Ind1@ wrote: >> >> A couple of more questions, >> >> I am calling my rules engine from a service and into the session i am >> inserting the business object. >> >> In my service class, I have a few helper functions, which I need to call >> from my drl file. >> >> How can I do that ? >> >> Thanks >> -D >> >> >> >> Corneil du Plessis wrote: >>> >>> You should initialise your globals and then pass them into the session. >>> Your rule file will have: >>> >>> global java.lang.String recipients >>> global java.lang.String to >>> global java.lang.String cc >>> >>> >>> On Mon, 2009-02-23 at 06:23 -0800, D1vy@@Ind1@ wrote: >>> >>>> Thanks for your help , Sudhir, >>>> >>>> I used >>>> >>>> rule >>>> when $a:A(b.z.s=="test"); >>>> then >>>> end >>>> >>>> And that solved my problem. >>>> >>>> But I would like to know one more information about global variables. >>>> >>>> package... >>>> dialect java >>>> import .., >>>> >>>> global java.lang.String recipients=&quot;divya(a)gmail.com&quot; >>>> global java.lang.String to=&quot;xyz(a)yahoo.com&quot; >>>> global java.lang.String cc=&quot;abc(a)gmail.com&quot; >>>> >>>> rule >>>> when when $a:A(b.z.s=="divya"); >>>> then >>>> $a.setRecipients(recipients); >>>> $a.setTo(to); >>>> $a.setCC(cc); >>>> update($a) >>>> end >>>> >>>> Is this feasible with Drools.

Hi, I am planning to use Drools - JBoss Rules Engine. My requirement is to disburse mails from my application to different groups based on various criteria. I want to use Drools here. My object structure is as follows: class A{ String B = ""; B b; C c; } Hence Obj A has embedded objects within it, and obj B and C further has embedded objects. class B { String X; Z z; } class Z{ String t; String s; } The decision on sending the mails based on the fields in embedded objects of A. I pass instance of A to Drools Format of drl file: package...; import ..; rule "Test" when $a:A(B(Z(s == "testvalue"))) then $a.setSomething(); update($a); end I wanted to know if this (accessing fields in embedded/child object) is feasible with Drools. I get an error saying "UNable to compile myfile.drl when i try to fo this. Could some one look into this issue and let me know the reason for this ?
