app-dev 'toe in water' help please

by dhartford

Hey all, I'm trying to dip some toes into the water with Drools, and have an application that would be a good start but having some understanding/lacking an appropriate example issue. The application context, let's say, is Mortgages, and already using the Mortgage rules that are stored in a running instance of Guvnor. Going back to 'toe in water', lets assume that all 'facts' are loaded on call (so nothing is pre-loaded, all data to run a rule is supplied at the time the rule is called). This is to make it easier to get started without jumping all-in just yet ;-) Using the mortgage business rule 'CreditApproval' that is already loaded into Guvnor, I can see passing the Application object, with the creditRating field/fact to a rule. However, instead of populating and returning a loanApplication object, how would I return just the decision/end result of a rule if it was only one value (the approved/not approved decision) from the java app? KnowledgeBase is loaded from the java app, but struggling with StatefulKnowledgeSession versus StatelessKnowledgeSession and how to simply get back the rule decision value (again, preferably without a specific object if it is only one value)? I'm also looking to only fire/execute one rule at a time for now until we get comfortable - any help for an app developer trying to ease their way into drools? Sorry if I not overly clear, still trying to learn the appropriate terminology :-) -Darren -- View this message in context: http://drools.46999.n3.nabble.com/app-dev-toe-in-water-help-please-tp3249...

Effective Dating of Rules

by MaverickDrools

Is there a way to effective date a rule through a program? Requirement: without using the Guvnor UI to write the rules, trying to upload a .drl file using REST APIs which already has rules specified "without" the date-effective/date-expire attributes. Is there a way to maintain versions that could be used by effective dating the entire package itself? Or in general, how do we effective date the rules in Guvnor without using date-effective attributes for rules and create a knowledgebase from the package based on the current date? Thanks -- View this message in context: http://drools.46999.n3.nabble.com/Effective-Dating-of-Rules-tp4022422.html Sent from the Drools: User forum mailing list archive at Nabble.com.

drools-solver results question

by Andrew Waterman

Hello, I'm starting to work with the drools-solver to help on a gaming project. Basically, we have a game that works in two modes: 1) a competitive game where humans (or agents) compete with one another on a well defined game board to achieve 24 points by using three (or four) agricultural development tokens. 2. A puzzle, where all 4 players work cooperatively to create an equitable solution, where all 4 players win with at least 24 points by means of our agricultural development tokens. I am starting to work with drools-solver to address the puzzle part of our game. Basically, we are interested in having the solver do two things for us: a) find the optimal solution for our game/puzzle, based upon our requirements [this part seems quite straightforward] and b) getting the total number of solutions that satisfy our constraints. We would like, as well, to be able to inspect these other, sub-optimal, solutions, in order to explore our game and puzzle further. From my reading of the "Solver" API , it looks like we will only be able to get the optimal solution. Does anyone have any suggestions for a workaround in this case? Or is there some functionality in the solver that I am missing? I look forward to your feedback. best wishes, Andrew --------------------------------- Andrew Waterman San Cristóbal de las Casas, Chiapas, Mexico

Need help with setFocus

by new2drools

Hi All, Need some help with understanding setFocus. I have the following use case: if (condition1) { if (condition2) { } else if (condition3) { } else if (condition 4) { } } if (condition5) { if (condition2) { } else if (condition3) { } else if (condition 4) { } } I created 3 rules (rule2, rule3, rule4) for checking condition2, condition3, condition4 and created 1 agenda group (groupX) for them. I created 2 rules (rule1, rule5) for checking condition1, condition5 and created 1 agenda group(groupY) for them. rule "rule1" agenda-group "groupY" when // then drools.setFocus("groupX"); end rule "rule3" agenda-group "groupX" activation-group "someActiveGroup" when // then // end >From the java code: ksession.getAgenda().getAgendaGroup("groupY").setFocus(); Problem: The first time, drools.setFocus("groupX") is invoked, I see that it's working fine. rule2 or rule3 or rule4 get triggered. But, the SECOND time that drools.setFocus("groupX") is invoked, I don't see that any rule in agenda-group groupX is being invoked...even though one of the rule's LHS explicitly matches...thinking that the activation-group is cancelling all the activation's (after one rule in that activation group is fired), I even removed the activation-group statement. But, it didn't help...ideally, I would like to bunch rule2, rule3, rule4 in one activation group. Can you please let me know as to why the second invocation of setFocus is not working? I even tried to remove everything in LHS of rule2/3/4, to see if the second invocation would work...it doesn't... Thanks!! -- View this message in context: http://www.nabble.com/Need-help-with-setFocus-tp24177742p24177742.html Sent from the drools - user mailing list archive at Nabble.com.

Drools beginner - unable to resolve method using strict-mode

by Stefan Schuster

Hi, I'm new to drools, and I made my first steps using the very nice video-tutorial "Build Pong in 13 minutes using JBoss Drools" found here: http://www.youtube.com/watch?v=Omj4PR3v-nI Eclipse shows building errors, but Pong start anyway. What does this error mean? in move.drl there is following rule: *<rule "Move Bat Up" timer(expr: bat.speed, bat.speed) no-loop when* * ui : PongUI( ready == true )* * ( KeyPressed( keyText == "A" ) and bat : Bat( playerId == PlayerId.PlayerOne, y > pconf.padding + pconf.sideLineWidth )* * or* * KeyPressed( keyText == "K" ) and bat : Bat( playerId == PlayerId.PlayerTwo, y > pconf.padding + pconf.sideLineWidth ) ) * * td : TableDirty( ) * *then * * tableG = ui.getTablePanel().getTableG();* * tableG.setColor( Color.BLACK ); // background* * tableG.fillRect( bat.x, bat.y, bat.width, bat.height );* * * * modify( bat ) { y = bat.y - 2 };* * tableG.setColor( Color.WHITE ); // background* * tableG.fillRect( bat.x, bat.y, bat.width, bat.height ); * * modify( td ) { dirty = true };* *end* the error message is: [Error: unable to resolve method using strict-mode: org.drools.spi.KnowledgeHelper.td<http://org.drools.spi.knowledgehelper.td/> ()] [Near : {... @Modify with( td ) { dirty = true }; ....}] in another File (ui.drl) TableDirty is defined: *declare TableDirty* * @propertyReactive* * dirty : boolean* *end* Any ideas what this error message means? And why can I start pong despite this error? Thanks a lot for helping me Stefan

conways game of life

by Mark Proctor

For anyone looking for a good and complex example on how to write rules properly, please look at Conways Game of Life in drools-examples, for extra bonus points compare it to the old version in M1. You'll see nearly all the logic is moved from java to the drl and we have removed the need for nested objects by using objects relaitionally, which also allows us to exploit cross products to drive the application.
