kie-drools-wb-6.0.1 : view "artifact repository" is empty

by jps

Hello, The artifact repository view in drools-wb is suddenly empty :( after having uploaded a new jar. Before this operation, I had 3 artifacts that were listed .. I try to redeploy the app, restart jboss, delete JBOSS_HOME/bin/repository and start again ... but still the list of artifact in the repository is empty, although i can see it's not empty on the disk in JBOSS_HOME/bin/repository/kie/... Something has been corrupted somewhere. But I'm stuck. Any idea or suggestions ? What can prevent drools-wb from getting the repo data ? Thanks jps -- View this message in context: http://drools.46999.n3.nabble.com/kie-drools-wb-6-0-1-view-artifact-repos... Sent from the Drools: User forum mailing list archive at Nabble.com.

Rules not picked when packaged inside the JAR

by ash316

I am working on DROOLS 6.0.1 application. I have my rule files (*.drl) packaged inside a separate project which is included as a jar file as a maven dependency. When I deploy my project, KIEModule is not able to find the rules files (which are packaged inside the jar above). I am not getting an error though but rules are not getting fired.If I manually place the rules files under classpath say WEB-INF/rules/*.drl they are detected and rules are executed.I was under impression that KIEmodules are auto discovered from anywhere in classpath.Any pointers are appreciated. This is general question hence I have not included the comprehensive code files. Everything start working once I place the *.drl files in the classpath (take them outside of jar).I have opened the JIRA issue @ Link <https://issues.jboss.org/browse/DROOLS-466> Thanks -- View this message in context: http://drools.46999.n3.nabble.com/Rules-not-picked-when-packaged-inside-t...

Workbench and GIT Repo High Availability

by Zahid Ahmed

Hi, We are in a process of setting up a centralized drools6 Workbench in our organization. This way we can keep our assets and artefacts in a central location. We will make this central Workbench clustered for high availability. I have a few queries in regard to clustering the Workbench. Problem Statement As workbench is using GIT, this means we need to have an enterprise level GIT repository where all the assets get stored for Workbench. As GIT is file-system based , it in turn, calls for a clustered GIT server within the organization. Our organization will prefer to have a private GIT repository hosted within office network which is highly available and wants to avoid any cost for GIT repository setup. 1. I want to know how to make Workbench highly available , with GIT also Highly available. Is chapter# 18 VFS CLUSTERING is the answer to high available GIT and WORKBENCH both ? or is there any other way to make GIT repository highly available. 2. Will ZooKeeper and Helix be enough to make the clustered environment for both Workbench with its GIT repo ? Regards, Zahid Ahmed

Drools Planner: Vehicle routing problems

by davidglassborow

Hi, as discussed the other day with Ge0ffrey on IRC, I've been trying to get some vehicle routing done using the new TSP / chaining functionality in drools planner. I've written an example, but am having problems with the chaining of jobs together. After pulling my hair out, I've put together an example into my fork of planner, showing a simplified example of how I am approaching it, and the problem that can be replicated. https://github.com/davidglassborow/drools-planner/tree/vehicle_routing It is a very simple console app along the same lines as the hello world example for NQueens. On running it will print out the chains, and you will see the some Jobs appear more than once in the same list. On the planning variable it seems to be get assigned in front of itself, I've put some notes in the source, and checked that the same doesn't occur in your TSP example. I'm not sure if its a bug in the way I've setup things, or whether its an issue in the chain move code. Greatly appreciated if anybody in the know gets a chance to have a look.

Workbench: Error after cloning repository

by Steinmetz, Jean-Philippe

Hello, I have successfully cloned an existing repository containing a maven kmodule project. Unfortunately when I attempt to open any of the DRL files in the workbench (6.0.1.Final) I get the following error: Unable to complete your request. The following exception occurred: java.lang.ClassNotFoundException:org.openxmlformats.schemas.officeDocument.x2006.docPropsVTypes.CTArray from [Module "deployment.kie-drools-wb.war:main" from Service Module Loader]. This error does not happen if I load any of the files in the demo project. The DRL files range from complex to very simple. They all use the mvel dialect and import the following globals. /** The Camel context used when handling input/output. */ global CamelContext camelContext; /** The application configuration. */ global Config config; /** A reference to the current knowledge base. */ global KieBase kBase; /** A reference to the current session. */ global KieSession kSession; /** The common logging utility. */ global org.slf4j.Logger logger; Outside of this there is nothing special to them. Has anyone seen this? Thanks, Jean-Philippe

Re: [rules-users] Compilation errors in Drools examples

by rjh

I have the same problem. It seems like the drool eclipse plugin can't recognize third party classes (any jar files besides those within JRE runtime and Drools runtime). Despite of the error messages, you can execute the java application correctly. However, I have asked around in this forum, in jira, and writing personal email to Kris Verlaenen and Mario Fusco, but no response at all!! Below are my posts regarding this problem: http://drools.46999.n3.nabble.com/rules-users-Drools-eclipse-plugin-probl... https://issues.jboss.org/browse/DROOLS-472 -- View this message in context: http://drools.46999.n3.nabble.com/Compilation-errors-in-Drools-examples-t...

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
