HTTP 401 Unauthorized when using KIE API on Workbench M2 repository

by Patel, Ronak (Autonomy)

I'm having trouble authenticating to access the Workbench Maven repository through the KIE API (kie-ci). My code is the following and fails on the second line with an exception that says something like module not found. I see the more specific 401 error in the local Maven repository in the resolver-status.properties file. KieServices ks = KieServices.Factory.get(); KieContainer kContainer = ks.newKieContainer(ks.newReleaseId("com.hp.pa.sample", "realestate", "LATEST")); I've tried putting in my settings.xml file both suggestions in https://bugzilla.redhat.com/show_bug.cgi?id=1059584#c4 (also saw the preemptive one in https://bugzilla.redhat.com/show_bug.cgi?id=1037556 and other threads/forums and bug reports), but I continue to get the same error. I did some further investigation using Fiddler and I see that the credentials are not being included in the HTTP request the code sends for resources in the Workbench Maven repository. I was expecting the basic authentication header to be in here. The HTTP request always looks like this (server name changed for security reasons): GET http://kiewbserver:8080/kie-drools-wb/maven2/com/hp/pa/sample/realestate/... HTTP/1.1 Host: kiewbserver:8080 Pragma: no-cache Cache-Control: no-cache, no-store Accept-Encoding: gzip Connection: keep-alive Connection: keep-alive Accept: */* User-Agent: Aether And the response is a typical HTTP/1.1 401 Unauthorized with the standard JBoss error page as the body. Using the composer feature in Fiddler, if I issue this same request with the basic authentication header included, it works, returning an HTTP 200 response with the requested file. If I remove the authentication requirement from the Maven repository using the workaround described in bug 1059584 (referenced above), all my code works fine. I followed the procedure to create a user for the Workbench on JBoss AS that is demonstrated in the start of this video: http://www.youtube.com/watch?v=vj3MNmiUnvY. That's the user whose credentials I've tried putting in my settings.xml. Is there anything else that needs to be done on the server side? Any other ideas on what I may have missed or how to debug this further? Thank you, Ronak Patel Software Designer HP Autonomy

NullPointerException when calling ScoreDirector.beforeEntityAdded with new Vehicle

by Hagai

Using OptaPlanner 6.0.1.Final with problem like vehiclerouting. In vehiclerouting the Vehicle and Customer are both planning entities. They both implements the Standstill interface that is annotated with @PlanningEntity and their collections are annotated with @PlanningEntityCollectionProperty on the solution class. Flowing the code of VehicleRoutingPanel.insertLocationAndCustomer to insert a new Vehicle to the solution, my code is failing when the new Vehicle is reported to the score director: scoreDirector.beforeEntityAdded(newVehicle); The exception is NullPointerException at org.optaplanner.core.impl.domain.variable.listener.PlanningVariableListenerSupport.beforeEntityAdded(PlanningVariableListenerSupport.java:54) It looks like the PlanningVariableListenerSupport.entityVariableListenerMap does not have item for the Vehicle entity, there is only one item for the Customer entity in this map. I get the same problem when calling ScoreDirector.beforeEntityRemoved to remove a Vehicle. Is this a bug or do I need to handle Vehicle entities differently? -- View this message in context: http://drools.46999.n3.nabble.com/NullPointerException-when-calling-Score...

How to implement immovable planning entities for vehicle routing problem?

by Hagai

I am implementing a vehiclerouting like solution with OptaPlanner 6.0.1.Final. According to the documentation for continuous planning, the way to 'lock' parts of the solution is by declaring a movableEntitySelectionFilter on the planning entity: Section 14.3.1. Immovable planning entities. However, this does not work well with chained entities where parts of the solution is calculated, like in the vehiclerouting example. For example, let's assume the following chains, where [Customer A] and [Customer C] are immovable: [Vehicle 1] <- *[Customer A]* <- [Customer B] [Vehicle 2] <- *[Customer C]* <- [Customer D] Even if we filter immovable entities, a move to set the variable [Vehicle 2] as previous standstill to [Customer B] can be selected with the following result that changes the immovable entity [Customer C]: [Vehicle 1] <- *[Customer A]* [Vehicle 2] <- [Customer B] <- *[Customer C]* <- [Customer D] A workaround is to filter moves with immovable entities as well as moves with immovable variables (variables are also entities). However, this can only work when immovable entities are placed at the beginning of chines before any movable entities. Is there a better way to implement immovable planning entities for vehicle routing problem? -- View this message in context: http://drools.46999.n3.nabble.com/How-to-implement-immovable-planning-ent...

Development lifecycle

by Branham, Jeremy [HR]

I am planning a new Drools architecture, and looking for the best way to migrate Drools rules through a series of environments. Our typical SDLC involves an initial DEV environment, then migrating to one of several TEST environments, then to an ORT environment, then finally to a PROD environment. The question has been asked a couple times, looking through the mail archives, but I'm curious if there have been any recent changes that could improve the development lifecycle. I've read we could just use the import/export function, or the following two options - Mentions Jackrabbit http://article.gmane.org/gmane.comp.java.drools.user/25097/match=producti... Using the Rest interface https://community.jboss.org/wiki/PublishDroolsartifactsfromaproductionenv... Anything else, or any best practice for this? Thanks! Jeremy D.

Any form of "groub by" or "distinct" in accumulate/collect ?

by Ephemeris Lappis

Hello. Perhaps that my question has few sense or none... I've an object graph with say A, B and C. A has one or many B, that has one or many C. I can navigate through the relations between my objects in both direction. For example, I can do fo any instance of C : c.b.a (or c.getB().getA())... My initial input facts or only C objects, and I'd like to identify all the distinct A instances, and insert them into my working memory, as they participate to global rules. I've been looking for some forms of accumulate or collect, but I've not found a correct way to do it. Some help ? Thanks Regards. -- View this message in context: http://drools.46999.n3.nabble.com/Any-form-of-groub-by-or-distinct-in-acc... Sent from the Drools: User forum mailing list archive at Nabble.com.

Multiple threads for KieBuilder

by RichardAmbridge

Hi, We have over 20000 rules in our drools implementation. In drools 5 we could build multiple packages in different threads and then create a Knowledge base joining all those packages together. e.g. Thread: knowledgeB = KnowledgeBuilderFactory.newKnowledgeBuilder(); knowledgeB.add(ResourceFactory.newReaderResource(new StringReader(sb.toString())), ResourceType.DRL); Then in the main compiler, once all threads have finished KnowledgeBase knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase(conf); for each thread: knowledgeBase.addKnowledgePackages(thrds[t].getKnowledgeB().getKnowledgePackages()); I can't seem to find anyway to do that with the new KIE implementation. What I would like to do is something like: Thread: Create sb to have lots of rules KieServices kieServices = KieServices.Factory.get(); KieFileSystem kfs = kieServices.newKieFileSystem(); kfs.write("src/main/resources/rules.drl", sb.toString()); KieBuilder kieBuilder = kieServices.newKieBuilder(kfs); kieBuilder.buildAll(); ..check errors KieContainer kieContainer = kieServices.newKieContainer(kieBuilder.getKieModule().getReleaseId()); KieBase kieBase = kieContainer.newKieBase(kieBaseConfiguration); In main compiling, create multiple threads, each with its own rule set. Then when all threads completed, take all the kieBase objects and merge into one base. then KieSession ksession=mergedKieBase.newKieSession(); We compile our rules offline and then load into our running servers. The compile server is a multicore server, but buildAll is single threaded. Is this possible? Many thanks for the support, Ric -- View this message in context: http://drools.46999.n3.nabble.com/Multiple-threads-for-KieBuilder-tp40294...
