Hi, What's the best way to have multiple kieBases dynamically on same/different KieFileSystem. let's say if i have 3 different drl(this can grow dynamically, so don't want to put in kconfig.xml)l files and i want all three of them to reside in different kiebases so that each session(stateful and stateless) created from the kiebase can have it's independent set of rules. Currently i a doing something like below: this.kFileSystem.write("com.sample" + filename + ".drl", content); this.kBuilder = this.kService.newKieBuilder(this.kFileSystem); this.kBuilder.buildAll(); // kieModule is automatically deployed to KieRepository if successfully built. if (this.kBuilder.getResults().hasMessages(Level.ERROR)) { throw new RuntimeException("Build Errors:\n" + this.kBuilder.getResults().toString()); } this.kContainer = this.kService.newKieContainer(this.kRepository.getDefaultReleaseId()); But here, everything goes in to the same knowledgeBase. The actual problems i am trying to solve are below : 1) If i'll rebuild 1 kieBuilder and kieContainer, others won't get affected and users can work on them at the same time during runtime. 2) For the stateless sessions, there's no getAgendaGroup(name).setFocus(), so it won't have to execute all the rules in the universal kieBase in my case.

Thanks Mark for the reply. you mean something like : KieServices kieServices = KieServices.Factory.get(); KieModuleModel kieModuleModel = kieServices.newKieModuleModel(); for( File ruleFile : ruleFiles) { KieBaseModel kieBaseModel1 = kieModuleModel.newKieBaseModel( "KBase1 ") .setDefault( true ) .setEqualsBehavior( EqualityBehaviorOption.EQUALITY ) .setEventProcessingMode( EventProcessingOption.STREAM ); KieBaseModel1.addPackage(java.lang.String s); ... } kfs.writeKModuleXML(kieModuleModel .toXML()); this.kieBuilder = ks.newKieBuilder(kfs).buildAll(); this.kContainer = this.kService.newKieContainer(this.kRepository.getDefaultReleaseId()); biut wouldn't that create another jar ? And if some new ruleFile come, then do i have to create all the kieBases again or can i just create the new kieBase? And if i need to modify any of the drl file, then will it rebuild the whole kieBuilder ? -- View this message in context: http://drools.46999.n3.nabble.com/Best-way-to-have-multiple-kieBase-dynam...

Sorry for the confusion, what i actually meant was : lets say i started my application and with the sample code i wrote above, i created n kieBases and everything works fine, but now in the middle i want to create another kieBase and deploy a new drl file in that kieBase on the fly, and want to deploy on the same application or module which is running. Do i need to create a new jar now ? Or can i write in the same kieFileSystem and buildAll ? -- View this message in context: http://drools.46999.n3.nabble.com/Best-way-to-have-multiple-kieBase-dynam...
