I'm using Drools 5.3.0 I'd like to find out if the following scenario is possible: - Include the repository_export.zip file inside my application WAR file. This way, Guvnor won't be necessary. - Provide a special upload page just like Guvnor's Import/Export to upload a completely new repository_export.zip file when rules have changed. I haven't been able to find a way to read a repository_export.zip file with the current API. They only talk about drl, pkg, etc..etc but no zip files. I could potentially take the zip file, unzip it to an XML and maybe read this file?? Any ideas would be really helpful.

Starting optaplanner with your own initialized solution

by paavanm

I have a relatively simple question. How do I have OptaPlanner use my own initialized solution as a starting point instead of having a construction heuristic create one? Does this have to be done with a custom SolverPhase? A little more detail on what I'm trying to do: I am scheduling a series of classes and related activities on a calendar. Let's say I have some class BA101 that occurs several times a week (these classes are immovable entities). There are homeworks, exams etc. associated with these classes which I need to schedule. E.g. on Feb 1st, a homework might be due, or on Mar 1st, there might be an exam. So I need to schedule time to do the homework or time to study for the exam. My initial solution for this would be very simple: I would schedule the homework/study time at the same time of the class itself, and let optaplanner move it around till it meets my hard & soft constraints. However, when I tried to do that (i.e. give my homework/study tasks an actual start time instead of just leaving the start time as null), OptaPlanner fell right through without actually making any moves to find the best score. How do I do this? This is my config at the moment, pretty basic (tried this with & without the construction heuristic; same result): <?xml version="1.0" encoding="UTF-8"?> <solver> <solutionClass>com.copilot.optaplanner.domain.ActivityScheduler</solutionClass> <planningEntityClass>com.copilot.optaplanner.domain.Activity</planningEntityClass> <scoreDirectorFactory> <scoreDefinitionType>HARD_SOFT</scoreDefinitionType> <simpleScoreCalculatorClass>com.copilot.optaplanner.solver.score.ActivitySchedulingSimpleScoreCalculator</simpleScoreCalculatorClass> </scoreDirectorFactory> <termination> <maximumSecondsSpend>10</maximumSecondsSpend> </termination> <constructionHeuristic> <constructionHeuristicType>FIRST_FIT</constructionHeuristicType> </constructionHeuristic> <localSearch> <acceptor> <entityTabuSize>7</entityTabuSize> </acceptor> <forager> <acceptedCountLimit>1000</acceptedCountLimit> </forager> </localSearch> </solver> Thanks for any assistance. -- View this message in context: http://drools.46999.n3.nabble.com/Starting-optaplanner-with-your-own-init...

drools verifier problem

by Jean-Christophe Fortier

Hi, I'm trying to use the verifier with my rules on drools 5.6 and I got an exception : org.drools.verifier.visitor.UnknownDescriptionException: Descr ( class org.drools.lang.descr.MVELExprDescr ) is unknown to drools verifier. I checked in the source code and this type of descriptor is indeed not handled yet. Do you know if it's fixed in 6.1? There is also this JIRA that could be useful https://issues.jboss.org/browse/JBRULES-3641 Please let me know of any development. Thx Jean-Christophe Fortier Concepteur de logiciel Software Developer first make it work, then make it better [cid:image001.png@01CD3FEF.190AE350] 895 rue De La Gauchetière Ouest, Suite 300, C.P. 48, Montréal (Quebec), H3B 4G1 Tel: 514-636-6365 x.5387 Fax: 514-636-23626

Drools Mailing List migration to Google Groups

by Mark Proctor

Drools community member, The Drools team are moving the rules-usesrs and rules-dev list to Google Groups. This will allow users to have a combined email and web access to the group. New Forum Information : http://drools.org/community/forum.html (click link to view) The rules-users mailing list has become high volume and it seems natural to split the group into those asking for help with setup, configuration, installation and administration and those who are asking for help with authoring and executing of rules. For this reason rules-users will be split into two groups - drools-setup and drools-usage. Drools Setup - https://groups.google.com/forum/#!forum/drools-setup (click link to subscribe) Drools Usage - https://groups.google.com/forum/#!forum/drools-usage (click link to subscribe) The rules-dev mailing list will move to drools-development. Drools Development - https://groups.google.com/forum/#!forum/drools-development (click link to subscribe) Google Groups limits the number of invitations, so we were unable to send invitations. For this reason you will need to manually subscribe. The Drools Team

Drools bpmn gateway constraints questions

by mattmadhavan

Hello, I am trying create a few constraints (XOR). I have a .DRL file with 3 agenda-group. I am also using a custom evaluator and few global static functions. Mine is a Stateless Session with bunch of records (Caner records) 1. How do I refer to the current fact? - Can I do something like this? *$cancerRecord : CancerRecord ()* 2. How do I invoke external functions? Can I do something like *inlist* ($cancerRecord.PRIMARY_SITE, "C500, C501, C502, C503, C504, C505, C506, C508, C509") *containsAny* (kcontext, $cancerRecord, "505101,505102,505103,505104,505105,505106,505107,505108") *not inlist *($cancerRecord.PRIMARY_SITE, "C500, C501, C502, C503, C504, C505, C506, C508, C509") *not containsAny *(kcontext, $cancerRecord, "505101,505102,505103,505104,505105,505106,505107,505108") *Please note that inlist and containsAny are valid functions that work. But I am not able to import tham within the constrains.* I not able to locate any documentation in this. Can some one point me to the right documentation. I have been stuck on this for couple of days. Any help is appreciated. Thanks in advance!

Re: [rules-users] DROOLS 5.6.0 Final Decision Table PermGen space OutOfMemoryError

Mark, thanks for responding. Do you have a recommendation as to how much I should increase the perm gen space? Also, is there anything else I can do to run my decision tables more efficiently?

Kie-Spring Issue, not able to created Session as "prototype"

by mattmadhavan

Hello, I have the following kie-spring xml definition to test my custom evaluater. Please note the * type="stateless" scope="prototype"* in the xml configuration. Everytime this session is looked up, I want a new instance of the StatelessKieSession. I am getting the same instance for both the look ups! Looks like the session bean is created as a Singleton even though I specified prototype scope. I really need to create prototype version of my StetelessKieSession on demand ( I am using Camel routes) as I increase the number of JMS clients to process the load. This is a critical feature I really require. Any ideas please? Seems to that kie-spring is not really mature enough! Thanks in advance!
