How to read XML using XMLPackageReader-Drools-compiler.5.2.1.final?

by Praveen

Hi, I am using Drools-compiler.5.2.1.final. I am trying to convert an drl to xml and vice versa using DrlParser, DrlDumper, XMLPackageReader and XML Dumper. Drl to XML conversion works fine but XML to Drl throws NPE. I have placed the XML file under a folder called sample. NPE is thrown at line 5.. Also attached is the exception. Please suggest. TIA. Reader source = new InputStreamReader( DroolsConversionHelper.class.getResourceAsStream(xmlFileName)); PackageBuilderConfiguration conf = new PackageBuilderConfiguration(); XmlPackageReader reader = new XmlPackageReader(conf.getSemanticModules()); DrlDumper dumper = new DrlDumper(); //line 5 reader.read(source); PackageDescr descr = reader.getPackageDescr(); String test = dumper.dump(descr); System.out.println(test); java.lang.NullPointerException at org.drools.xml.ExtensibleXmlParser.resolveSchema(ExtensibleXmlParser.java:696) at org.drools.xml.ExtensibleXmlParser.resolveEntity(ExtensibleXmlParser.java:622) at com.sun.org.apache.xerces.internal.util.EntityResolverWrapper.resolveEntity(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLEntityManager.resolveEntity(Unknown Source) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.resolveDocument(Unknown Source) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.findSchemaGrammar(Unknown Source) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.handleStartElement(Unknown Source) Regards, Praveen. -- View this message in context: http://drools.46999.n3.nabble.com/How-to-read-XML-using-XMLPackageReader-...

Migration to Drools 6 and Workbench from Guvnor 5.5?

by dunnlow

We are currently using Drools 5.5 with Guvnor and investigating ways to migrate to Drools 6 and workbench. Thus far, the only option I have found is to re-add each rule (i.e. no "Import Repository" option). Has anyone made this migration and what was your method? Is there any sort of migration guide / tool? I saw this question asked back in October (http://drools.46999.n3.nabble.com/Upgrade-Guvnor-5-5-0-repository-to-Droo...) but... Thanks for any insight. -J -- View this message in context: http://drools.46999.n3.nabble.com/Migration-to-Drools-6-and-Workbench-fro...

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.
