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. In wireshark I see that an HTTP PUT call is made and the answer is: HTTP/1.1 405 Method Not Allowed Server: Apache-Coyote/1.1 Pragma: No-cache Cache-Control: no-cache Expires: Thu, 01 Jan 1970 01:00:00 CET Content-Type: text/html;charset=utf-8 Content-Length: 1176 Date: Wed, 28 May 2014 12:00:44 GMT <html><head><title>JBoss Web/7.2.2.Final-redhat-1 - JBWEB000064: Error report</title> </head><body> JBWEB000065: HTTP Status 405 - HTTP method PUT is not supported by this URL <HR size="1" noshade="noshade">*JBWEB000309: type* JBWEB000067: Status report*JBWEB000068: message* HTTP method PUT is not supported by this URL*JBWEB000069: description* JBWEB000125: The specified HTTP method is not allowed for the requested resource.<HR size="1" noshade="noshade"> JBoss Web/7.2.2.Final-redhat-1 </body></html> in a more readable format: JBWEB000065: HTTP Status 405 - HTTP method PUT is not supported by this URL JBWEB000309: type JBWEB000067: Status report JBWEB000068: message HTTP method PUT is not supported by this URL JBWEB000069: description JBWEB000125: The specified HTTP method is not allowed for the requested resource.

Abstraction between rules and data model?

by Péter Gergely, Horváth

Hi All, We are evaluating Drools 6 for our use case, and face challenges where we would need some ideas from more experienced users of Drools. We have an application with a massive code base and a large number of model (entity) classes. We are in the process of moving away from inherited legacy technologies and refactoring the old code base. As a part of this work we would like extract some of the hard-coded business logic to external rules, that is why we are looking at Drools as a potential solution. What we would like to have is some kind of abstraction or mapping between actual entities and rules the business users can define so that they do not have to know the _exact_ details of the data model (field names, precise relations etc). This would be important for us so that we can refactor the old model classes without affecting business rules; also it would make life easier for the business users. While IDE support might make refactoring easier, we definitely want to have a separation between rules and entities. Given our situation, writing and maintaining "stable" wrapper/adapter classes for the sole purpose of rule processing is out of question. I have checked the documentation of Drools DSL support and for me it seems to be overkill for our use case: we do not really need a custom language, but simply an abstraction between rules and the data model classes. What I could imagine is a piece of code, (a custom property resolver? - no sure how it is called) which maps property expressions to actual properties based on a custom annotation on the entity class or something like that, so that a rule containing "Foo.bars" expression does not have to change even if we decide to rename "Foo.bars" to "Foo.barList" in the model classes. (This was just a simple example of a potential use cases) Could you please share your thoughts on this topic and point me into the right direction? Thanks, Peter

"Cannot find KieModule" with kieServices.newKieContainer() with LATEST or RELEASE instead of explicit version number (eg: 0.0.1)

by Matteo Mortari

Hello, in the hope this could save time if someone has been experiencing same issue. Drools 6.0.1.Final I had message "Cannot find KieModule" with kieServices.newKieContainer() with LATEST or RELEASE , instead of explicit version number (eg: 0.0.1) on a application where the KIE module Rule artifact project kjar has been locally-installed from remote Maven repository, that is the right hand side of this diagram: http://docs.jboss.org/drools/release/6.0.1.Final/drools-docs/html_single/... Meaning that before launching Application, I performed mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=com.acme:X:LATEST -DrepoUrl= http://nexus-hostname/nexus/content/repositories/releases/ Then: kieServices.newKieContainer() with LATEST, kieServices.newKieContainer() with RELEASE, failed with stack trace: Exception in thread "main" java.lang.RuntimeException: Cannot find KieModule: com.acme:X:RELEASE at org.drools.compiler.kie.builder.impl.KieServicesImpl.newKieContainer(KieServicesImpl.java:86) at (...) But kieServices.newKieContainer() with a fixed version, eg.: 0.0.2 did indeed worked OK, if installed in the local .m2 repository. To avoid this issue, I found only 3 possible workarounds 1 use mvn maven-dependency-plugin:go-offline but did not work all of the time 2 manually ensure maven-metadata-local.xml file is generate in local .m2 repository 3 just download manually .jar and .pom of the remote maven repo, and then install with mvn install:install-file In this case, of workaround kieServices.newKieContainer() works OK with all the version LATEST, RELEASE, and fixed version number. Raise jira DROOLS-419 with more details and example projects, please don't hate me if was just me missing something or not-Drools issue actually =P In my defense I had good intentions saving somebody's else time in case same strange behavior, which is really strange because to me it worked only with explicit fixed version number, and that was really bizarre ;) Hope this helps, Ciao MM

Problem in Drools Persistence: The sessioninfo is persisted, but all of my POJOs that still remain in the session aren't (table is created, but nothing is written into them)

by arcadyt＠gmail.com

Hi everybody! For demo purposes, there's a class Book that goes as follows: @Entity @Table(name="book") public class Book implements Serializable { @Id private String id; private String title; private String description; private Float unitcost; private String isbn; private Integer nbofpages; //Default ctor... getters & setters... toString... } I created a basic rule that checks if Book's title contains "Java" it's left in the session, otherwise it's retracted: dialect "mvel" import com.arcady.*; rule "not a java book" when b:Book(title.contains("Java")==false) then System.out.println("Yet another boring book... Retracting: " + b.toString()); retract(b); end So far, so good. Problem now is when trying to persist all the Drools + Book's instances that still remained in the session into MySQL database (I usedhttp://packtlib.packtpub.com/library/9781849511964/ch02lvl1sec17 as reference). After inserting 4 books as listed below into the session and firing all rules: Book javaBook1 = new Book("Java EE 7"); Book javaBook2 = new Book("Java Persistence API 2.1"); Book javaBook3 = new Book("Java SE 8"); Book csharpBook1 = new Book("C# 5.0"); I get in the output: Hibernate: insert into SessionInfo (lastModificationDate, rulesByteArray, startDate, OPTLOCK) values (?, ?, ?, ?) Hibernate: update SessionInfo set lastModificationDate=?, rulesByteArray=?, startDate=?, OPTLOCK=? where id=? and OPTLOCK=? Hibernate: update SessionInfo set lastModificationDate=?, rulesByteArray=?, startDate=?, OPTLOCK=? where id=? and OPTLOCK=? Hibernate: update SessionInfo set lastModificationDate=?, rulesByteArray=?, startDate=?, OPTLOCK=? where id=? and OPTLOCK=? Yet another boring book... Retracting: Book{id=304e76fd-3d9a-479b-b22d-a774d721df65, title='C# 5.0', description='Blabla', unitcost=0.0, isbn='ABC123', nbofpages=12345} Hibernate: update SessionInfo set lastModificationDate=?, rulesByteArray=?, startDate=?, OPTLOCK=? where id=? and OPTLOCK=? Thus the session was persisted 4 times, and indeed that's what also shows in the database in the sessioninfo table. Problem is Book's table is created with all the correct columns automatically but remains empty... What do you think causes this? Thanks a lot! -- Regards, Arcady Trembovler

Question about Fusion pseudoclock

by Natalia Iglesias de Amunategui

Hello, I am implementing temporal rules using drools fusión 6.0.1 and the new KIE services api. I insert facts into the kie session that include some DATE fields which I later use in the rules. I also insert events using the pseudoclock, so I guess that means that the timestamp is kept in long format. The consequence is that my temporal rules do not fire at all! I have no @timestamp annotation in the declare of the event, so Drools internal clock should be used as timestamp. I have displayed the value of the pseudoclock getCurrentTime method, and the output shows a date of 1970: I need to understand why the clock.getTime returns dates of 1970, maybe when this is solved the rules will fire with the internal event timestamp. (After that I have tried every possible combination: creating a date or long field in the event fact representing the timestamp, converting long to date and viceversa, but nothing seems to work..). I enclose here the initialization that I do of the kieContainer and session: public static void main(final String[] args) { try { // load up the knowledge base KieServices ks = KieServices.Factory.get(); KieContainer kContainer = ks.getKieClasspathContainer(); System.out.println(kContainer.verify().getMessages().toString()); // set stream mode as opposite to cloud mode KieBaseConfiguration kbconf = KieServices.Factory.get().newKieBaseConfiguration(); kbconf.setOption(EventProcessingOption.STREAM ); // set clock to pseudo clock to be able to advance it manually KieSessionConfiguration ksconf = KieServices.Factory.get().newKieSessionConfiguration(); ksconf.setOption(ClockTypeOption.get("pseudo")); // returns ksession from kiecontainer as defined in the kmodule.xml file KieSession kSession = kContainer.newKieSession("VAPSession", ksconf); // Insert test patients and related classes, dates are in long format to match pseudoclock final Patient p1 = new Patient( "MrJones", 45, 1, true,false,false,35.0, 5000,"None","Localized Infiltrates","Yes","None","S.Aureus",245,false, false, 0, true,new SimpleDateFormat("yyyy-MM-dd").parse("2014-05-31").getTime(),"", new SimpleDateFormat("yyyy-MM-dd").parse("2014-05-31").getTime(),false,false,fal se,false); kSession.insert( p1 ); // Insert test patients and related classes, dates are long format final Patient p2 = new Patient( "MissDaisy", 90, 1, true,false,true,37.0, 5000,"Purulent","Diffuse or Patchy Infiltrates","None","Heavy","S.Aureus",235,false, false, 0, true,new SimpleDateFormat("yyyy-MM-dd").parse("2014-05-31").getTime(),"", new SimpleDateFormat("yyyy-MM-dd").parse("2014-05-31").getTime(),false,false,tru e,false); kSession.insert( p2 ); // define and get a reference to the entry point EntryPoint nursingStream = kSession.getEntryPoint( "NursingStream" ); // define session clock SessionPseudoClock clock = kSession.getSessionClock(); // insert events // then, while inserting events, advance the clock as necessary: clock.advanceTime(24, TimeUnit.HOURS); CPIScore cpiScore1 = new CPIScore( p1,"diagnosis",7,ToDate(clock.getCurrentTime()) ); nursingStream.insert( cpiScore1 ); System.out.println(cpiScore1.getcpiScoreDate()); // day 2 clock.advanceTime( 24, TimeUnit.HOURS ); cpiScore1 = new CPIScore( p1,"follow-up",5,ToDate(clock.getCurrentTime()) ); nursingStream.insert( cpiScore1 ); System.out.println(cpiScore1.getcpiScoreDate()); // day 3 clock.advanceTime( 24, TimeUnit.HOURS ); cpiScore1 = new CPIScore( p1,"follow-up",5,ToDate(clock.getCurrentTime()) ); nursingStream.insert( cpiScore1 ); System.out.println(cpiScore1.getcpiScoreDate()); The fact classes have now long fields to represent Dates (I changed to see if that made a difference, it didnt). The event class has such a long field that can be defined as @timestamp but I rather prefer to use the internal event timestamp managed by Drools. So in my .DRL file Id like to have: declare CPIScore @role(event) end In my rules I compare the patient hospitalization date (defined as Date and later as Long in the fact class) with a stream of events , and I expect drools to extract the correct timestamp from the event. This cant happen if 1970 is the pseudoclock date. Please advice as about how to proceed, Im a bit lost at this point.

Possible bug with incremental compilation

by Federico Bertola

Hi all, executing the test in "drools/drools-compiler/src/test/java/org/drools/compiler/integrationtests/" all goes well except if i write a kmodule xml inside the KieFileSystem. Is this supposed to happen? I cannot add or remove a KieBase during incremental compilation, or I'm doing something dumb? I'm on Ubuntu 12.04 64bit java 1.7.0_55 Heres a simple test case: ######################################### @Test public void shouldRecompileWithNewBases() { String drl1 = "global java.util.List list\n" + "rule R1 when\n" + " $s : String() " + "then\n" + " list.add( \"a\" + $s );" + "end\n"; String drl2 = "global java.util.List list\n" + "rule R2 when\n" + " $s : String() " + "then\n" + " list.add( \"b\" + $s );" + "end\n"; ReleaseId releaseId1 = KieServices.Factory.get().newReleaseId( "it.mine", "test", "1.1"); ReleaseId releaseId2 = KieServices.Factory.get().newReleaseId( "it.mine", "test", "1.2"); KieServices ks = KieServices.Factory.get(); KieModuleModel kproj = ks.newKieModuleModel(); KieBaseModel kieBaseModel1 = kproj.newKieBaseModel("KBase1") .addPackage("it.mine.test"); kieBaseModel1.newKieSessionModel("KSession1").setDefault(true); KieFileSystem kfs = ks.newKieFileSystem(); KieBuilder kieBuilder = ks.newKieBuilder(kfs); kfs.generateAndWritePomXML(releaseId1); kfs.write("src/main/resources/it/mine/test/rule.drl", drl1); // FIXME: without this line all goes well. kfs.writeKModuleXML(kproj.toXML()); kieBuilder.buildAll(); assertEquals(0, kieBuilder.getResults().getMessages().size()); KieModule kieModule = kieBuilder.getKieModule(); assertEquals(releaseId1, kieModule.getReleaseId()); KieContainer kc = ks.newKieContainer(releaseId1); KieSession ksession = kc.newKieSession(); List<String> list = new ArrayList<String>(); ksession.setGlobal("list", list); ksession.insert("Foo"); ksession.fireAllRules(); list.clear(); kfs.generateAndWritePomXML(releaseId2); kfs.write("src/main/resources/it/mine/test2/rule.drl", drl2); IncrementalResults results = ((InternalKieBuilder) kieBuilder) .incrementalBuild(); assertEquals(0, results.getAddedMessages().size()); kieModule = kieBuilder.getKieModule(); assertEquals(releaseId2, kieModule.getReleaseId()); Results updateResults = kc.updateToVersion(releaseId2); assertEquals(0, updateResults.getMessages().size()); } ######################################### Heres the stack trace: ######################################### java.lang.NullPointerException at org.drools.compiler.kie.util.ChangeSetBuilder.build(ChangeSetBuilder.java:51) at org.drools.compiler.kie.builder.impl.KieContainerImpl.update(KieContainerImpl.java:126) at org.drools.compiler.kie.builder.impl.KieContainerImpl.updateToVersion(KieContainerImpl.java:105) at it.mine.IncrementalCompilationTest.shouldRecompileWithNewBases(IncrementalCompilationTest.java:165) ######################################### Thanks for the help!

Using dynamic package names with Drools 6.0 Spring integration.

by Sunny Singh

Hello, I am trying to integrate Drools 6.0 with my application using Drools-Spring integration features. Issues faced: I need to define the knowledge bases in a spring context XML and make the package names to be dynamically passed into the knowledge bases using Spring Expression Language when the Spring container is created at the start-up. But, the package names are not being injected into the knowledge base when it is created by Drools framework. If I define the package names and hard-code them into the "packages" property of the kbase tag, it works. Could you please let me know if there is a way to make the package names being passed dynamically passed into the "packages" property of the kbase tag. This is because my client application would supply the packages names when the knowledge bases are setup and I am trying not to hard-code these. XML Configuration: <bean id="packageRepository" class="test.PackageRepository"> <property name="packages" value="packageA,packageB"/> </bean> <kie:kmodule id="kmodule"> <kie:kbase name="testKnowledgeBase" packages="#{packageRepository.packages}"/> </kie:kmodule> Thanks!

Not and forall operator behaviour

by rogerL

Are the two following statements not equivalent? forall($msg:Message() Message(this==$msg, sent==true, status!=State._INITIALIZED) ) not( Message(sent==false, status==State._INITIALIZED) ) My understanding is that they both ensure that there are no Message objects in WM with property 'sent' set to false and property 'status' set to State._INITIALIZED. In my situation, the 'forall' approach is working as expected, the 'not' approach fires once (when there are no Message objects in WM) and never again. Appreciate if anyone could shed light on this. -- View this message in context: http://drools.46999.n3.nabble.com/Not-and-forall-operator-behaviour-tp402...
