Hi, I have a requirement which is as 1. There are three rules lets say rule1, rule2 and rule3 2. rule1 says there is a person Age < 40 Age >= 20 Then do something 3. rule2 says there is a person Age < 60 Age >= 40 Then do something else 4. rule3 says there is a person Age >= 60 Then do something new Now I am feeding person object as whole as event based from other application. So the requirement in form of test cases is 1. Age = 22 - do something 2. Age = 25 - Nothing as rule1 is already triggered and "do something" done 3. Age = 42 - do something else 4. Age = 45 - Nothing as rule1 is already triggered and "do something else" done 4. Age = 65 - do something new 5. Age = 68 - nothing 6. Age = 25 - do something 7. Age = 45 - do something else Is there any way to do this using the guvnor UI? Thanks and regards, Chaturvedi Dewashish Nirvana Solutions

After numerous of different approaches I am looking for some help

by dBijkoo

I'm dealing with the problem and I am looking for some help. I thoroughly studied the documentation and tried several different approaches myself but can't seem to get it working the way i want it to work. Let me start by describing the problem: Observation has a duration which is a multiplication of 5 (minutes), besides this it has one or more required disciplines (explained later). ScheduleBlockPeriod is a period of 5 minutes which is connected to a scheduleBlock ScheduleBlock contains a list of disciplines which can be performed in this block (there can be 1..* scheduleBlocks) Explanation: An observation has to be planned into one or more scheduleBlockPeriod(s) since a observations duration can be bigger then a scheduleBlockPeriods period. I checked out the VRP application and based my model on that. The reason why scheduleBlockPeriod is chained has to do with the amount of periods there are. I will write a custom move at some point which limits the nextScheduleBlockperiod to only select a period which is from the same ScheduleBlock and is right after the current one. Below I added a classdiagram how i would want it to work: <http://drools.46999.n3.nabble.com/file/n4029842/planning_class_diagram_2.png> After I run a construction heuristic on the program implemented as described in the classdiagram it tells me the solution is uninitialized, which is obvious because it assigns 1 scheduleBlockPeriod to the Observation. Because the duration of the observation is 5 minutes(the same as the duration of a scheduleBlockPeriod). This makes the chained variable nextScheduleBlockPeriod null, which it should be since it is 1 scheduleBlockPeriod "long". So basically im wondering if there is some sort of work around for this or perhaps someone is able to tell me that I am totally modelling it the wrong way. -- View this message in context: http://drools.46999.n3.nabble.com/After-numerous-of-different-approaches-...

Activation-group ignored when working with events in Drools 6 ?

by kenota

It seems that activation-group rule attribute is ignored when rule works with events (@role(event)). Example rule file: declare LocalEvent @role(event) end rule "Rule1" activation-group "test" when $event : LocalEvent() then System.out.println("I am rule 1 " + $event); end rule "Rule2" activation-group "test" when $event : LocalEvent() then System.out.println("I am rule 2 " + $event); end If i create event and insert it into KieSession both rules are fired, if i remove @role(event) line then only one rule is fired. I am experiencing this behaviour in 6.0.1.Final and 6.1.0.Beta4, but seems like everything is working as expected in 5.5.0.Final. Is that expected behaviour or a bug? -- View this message in context: http://drools.46999.n3.nabble.com/Activation-group-ignored-when-working-w...

KnowledgeBuilderFactory.newKnowledgeBuilder(KnowledgeBase kbase) throws exception

by A. Craig West

I had some issues getting my codebase to work in Drools 5.6.0 (it worked in 5.5) so I am now trying the legacy api with 6.0.1Final. When I call: KnowledgeBuilderFactory.newKnowledgeBuilder(KnowledgeBase kbase) I get an exception: java.lang.ClassCastException: org.drools.impl.adapters.KnowledgeBaseAdapter cannot be cast to org.drools.core.impl.KnowledgeBaseImpl

ruleflow-group vs. agenda-group vs. activation-group ?

by Péter Gergely, Horváth

Hi All, I've been experimenting with agenda-group and ruleflow-group features and I am now a bit confused. The documentation states that agenda-group and ruleflow-group features have been merged, but I'm not sure how this relates to activation groups. ruleflow-groups used to be a rule-flow feature, driven by the .RF file, requiring JBPM engine behind the scenes. Agenda-group work without the presence of JBPM: does it mean we can use the RF file for visualizing the agenda-groups as well? Could someone please shed some light on the differences between these constructs? Which one is the currently recommended approach (when?) for controlling rule execution flow? Thanks, Peter

Sharing common rules between KieSession

by Péter Gergely, Horváth

Hi All, We develop a software used by multiple companies. A small part of the rules is slightly different for every single company. We would like to package all of the rules into the application, so the code should - based on environment information - decide, which ones to load (using KieClasspathContainer). KieServices kieServices = KieServices.Factory.get(); KieContainer kContainer = kieServices.getKieClasspathContainer(); KieSession kSession = kContainer.newKieSession("foo-company"); Since ~90% of the rules is the same, I'm wondering what the best approach could be in this situation: duplicating common rules in every KieSession package seems to be a very bad idea. Say I define a set of general rules in* rules.common* package and rules specific to company Foo (*rules.foo*) and Bar (*rules.bar*), is there any way to load and merge the two into a single KieSession? Could I somehow say, "please give me the rules from rules.common and rules.foo"? I know that I could use the low level APIs to load rule files individually, but that is something I would like to avoid. Is there any better solution for this? Thanks, Peter Is there any way to load multiple KieSessions and combine them into one? For example, if there are companies Foo and Bar, could I For the application should

How to use already saved compiled packages

by AnuRadha

Hi, We are using Drools 4.0.7 in our Insurance application(policies will be created). We are facing one issue with saved packages at run time. Using Jboss server on deployment all the rules are compiling and the .pkg files storing in a directory folder(eg. C:/Rules). On restart of Jboss server, now using the saved packages from C:/Rules. App is deploying properly, here while creating a new policy everything working fine. But if we go thru already existed policy the app is hanging at setting up facts. On debug one of the fact is 'PolicyImage' which is all the info of the policy will be there, here it is hanging up. But some times taking much time to setup facts. private void setupFacts(StatefulSession session, List facts) { try { List<FactHandle> factHandles = new ArrayList<FactHandle>(); for(int i=0; i < facts.size(); i++) { factHandles.add(session.insert(facts.get(i))); // here taking much time/hang } } finally { log.info("< setupFacts"); } } Can anybody help what could be the reasonfor this. -- View this message in context: http://drools.46999.n3.nabble.com/How-to-use-already-saved-compiled-packa...

Rules storage without Guvnor?

by Péter Gergely, Horváth

Hello All, We are evaluating Drools for our use case and would have a question for storing rules files. We are in a relatively constrained environment, where getting Guvnor up and running does not seems to be a valid option. Since we would only need the core repository functionality so that we can separate rule deployment from application deployments (and none of the advanced features like online editing etc), I think it would make more sense to have a light-weight alternative for storing the rule files. Being able to pick up rules from an NFS share of from a database CLOB field would be perfectly sufficient for us. I have worked with JBPM4 quite a lot, where the core engine contained support for versioned storage of the process definitions in the database itself [1]. Is there any similar feature in Drools, where the rules can be deployed to e.g. a database or any other repository solution, (without using Guvnor)? I haven't found too much details on this topic, but for me it seems that the only approach would be to have some custom logic, which programmatically checks for rule updates and re-creates the whole knowledgebase on any update. I am wondering whether there is any more sophisticated solution in Drools where at least update checking/rule reconfiguration could be delegated to the engine. Any inputs are appreciated. Thanks, Peter [1] http://docs.jboss.com/jbpm/v4/javadocs/org/jbpm/api/RepositoryService.html

About the Quest Of : How to push changes to cloned repo onKie-Workbench

by DonnieDarko

Hi: The ori question is here: http://drools.46999.n3.nabble.com/How-to-push-changes-to-cloned-repo-on-K... It send me this email after I reply it derectly; But this question confuse me fo a week, So i answer the email for looking more help quickly,forgive me After reading the origin prob, I think the question is We can clone the project from wb's git server, like git clone git://10.101.81.72:9418/uf-playground Take attention: 1.we use the git protocol to clone the git project 2.it do work well 3.we use git bash to clone the project(whatever u use other tools: git gui, eclipse egit plugin, svn git merger) 4.we can add files,we can commit local modified, we can create branches, but we cannot push the modifies to server/master，we cannot merge branches to master 5.i donot think the kie-config-cli is a good enough tool a.i use the jboss-eap-6 as my appserver,there is a exception about "address is already used" when i run the kie-config-cli.sh after i deploy Guvnor in the same machine b.i meet the same problem about: lllpcsd@lllpcsd-VirtualBox:~/drools_git_ws/uf-playground$ git push fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. so 1.this is about how to config Git security cer in Guvnor workbench 2.we just want to develop projects with git tool, just want to push/merge codes!!! 3.i don't get more information from the drools's document it say: org.uberfire.nio.git.ssh.cert.dir: Location of the directory .security where local certtificates will be stored. Default: working directory and then? and then? and then? we know the .security directory is located $work_dir/.security, we cannot get enough information about how to config things about Git's SSH key or security trust :< we know the github.com platform will advance us to set the SSH key to do developing works, but the Guvnor has no UI function to set this. May be I do the wrong thing about clone, May be I should clone the code with SSH, how to config ssh is always a problem May be these are all wrong action about how to use Guvnor correctly The drools's document is so powerful and so poor :< Help If you reply to this email, your message will be added to the discussion below: http://drools.46999.n3.nabble.com/How-to-push-changes-to-cloned-repo-on-K...

mvn deploy to workbench fails: Return code is: 405, ReasonPhrase:Method Not Allowed.

by jmterrettaz

Hi I have installed the Drools Workbench kie-drools-wb-distribution-wars-6.0.1.Final-jboss-as7.0.war on JBoss EAP 6.2. When I try to do a mvn deploy to the workbench it fails with "Return code is: 405, ReasonPhrase:Method Not Allowed." Here the distributionManagement section of the POM: <distributionManagement> <repository> <id>guvnor-m2-repo</id> <url>http://localhost:8080/kie-drools-wb/maven2/</url> </repository> </distributionManagement> I also defined the server as follow in my settings.xml : <servers> <server> <id>guvnor-m2-repo</id> <configuration> <httpHeaders> <property> <name>Authorization</name> <value>Basic xxxoffuscatedxxxxx =</value> </property> </httpHeaders> </configuration> </server> </servers> If I give a wrong Authorization value there I get a 401 non authorized, so I think the server is correctly configured.
