Disable JIT in Drools 6.2 with Java 8

由 最后都变了- 提交于 2019-12-08 16:41:34
We are working with Drools version 6.2.0.Final for parsing some of our rules. But sometimes when we have a lot of runs, Drools invokes the JIT compiler which is causing failures. We have this covered in our Junit tests and we are getting the following error java.lang.NoSuchMethodError: org.mvel2.compiler.BlankLiteral.<init>(Ljava/lang/String;)V at ConditionEvaluatoref4dc802b6174038b0307f5e6196e229.evaluate(Unknown Source) at org.drools.core.rule.constraint.MvelConstraint.evaluate(MvelConstraint.java:248) at org.drools.core.rule.constraint.MvelConstraint.isAllowed(MvelConstraint.java:204) at

Drools: how to retrieve the fact in response from Kie Execution Server?

问题 I am using Kie Execution Server 6.2 final and I have a simple rule file deployed on the server and I am accessing it through rest api. When I try to execute the rules, everything goes well, but I do not get newly inserted fact in the response. Here is my drl file rule "Odd Rule" dialect "mvel" when testRecord : TestRecord((integerValue & 1) == 1 && integerValue != 0 , testId: testRecordId , intValue :integerValue ) then System.out.println( "Odd Rule- Test ID "+ testId ); TestResult

问题 I have installed http://download.jboss.org/jbpm/release/6.4.0.Final/jbpm-6.4.0.Final-installer-full.zip found here http://www.jbpm.org/download/download.html and this is a self contained environment with ant and commands like: "ant install.demo". You end up with a nice environment for learning the kie workbench. This is great for learning, but I really want to take it to the next step which is to have a single wildfly server with ear/war file(s). I can't seem to find instructions or advice on

Deploy programatically created KIE-Drools-Artifact to Maven repository

问题 Is there a way to deploy a programatically created Drools 6 artifact to the underlying maven repository? I do NOT want to explicitly somehow call mvn deploy but do that from the program itself: public static void main(String[] args) { String ruleString = "rule \"TestRule\"\nthen\nSystem.out.println(\"This is a testrule.\");\nend"; KieServices kieServices = KieServices.Factory.get(); KieModuleModel kieModuleModel = kieServices.newKieModuleModel(); KieBaseModel kieBaseModel = kieModuleModel

Drools 6.4 KieScanner : How create and add Jar with rules in Maven?

由 谁都会走 提交于 2019-12-03 20:55:19
I am a beginner with Drools and Maven and I am facing a problem to load rules with KieScanner. The aim of the project is to be able to dynamically load rules in a permanent KieSession. I wonder if it is possible to manage rules with the KieFileSystem (not sure it is possible without a dispose of the session and starting another one leading to the lack of the previous inserted facts), but the good way is to use KieScanner. It seems this requires the creation of a Jar containing the rules and having a Maven ID (ReleaseId), but I could not find detailed documentation about creation of these Jar

Same way suggest me any API is regarding to that. Thanks in advance. Chris_F I interpret your question in two different ways. 1. Is it possible to write rules for Drools without using the KIE workbench? Yes, it should support importing rules so all you need to do is open up a text editor and start typing. The rules are written as text using a fairly simple
