Re: [rules-users] Best way to have multiple kieBase dynamically
each time you wish to update, you need to increase the model’s version. You can do that with your existing kiebuilder and kiefilesystem. Then buildAll and make sure it’s added to KieRepository (if it’s not done automated, I forget if it is or isn’t). Once the new jar is in the KieRepository you can call kieContainer.updateToJar; and it will upgrade the changed kiebases.

Re: [rules-users] Best way to have multiple kieBase dynamically
Thanks Mark, that's exactly i was thinking of. Because i don't have the permissions of deploying the jars on the fly. -- View this message in context: http://drools.46999.n3.nabble.com/Best-way-to-have-multiple-kieBase-dynamically-tp4028247p4028259.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Best way to have multiple kieBase dynamically
You need to specify the packages that the kiebase includes. That way different
resources can be assigned to different kiebases
KieBaseModel.addPackage(java.lang.String s);
In the xml it’s a comma separated list packages=“

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 in advance.

Re: [rules-users] Best way to have multiple kieBase dynamically
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 ?

Re: [rules-users] Best way to have multiple kieBase dynamically
take a look at this kmodule.xml. This is one maven project,and thus one jar,
but with 1..n named kiebases in it. Each kiebase selects resources from
different folders.
https://github.com/droolsjbpm/drools/blob/master/drools-examples/src/main/resources/META-INF/kmodule.xml
The model you are working with just creates the kmodule.xml that ends up in the
jar.
