问题 I have a project setup in KIE Workbench, version 6.5.0 and a KIE execution server 6.5.0 running, all on the same local Wildfly 10. It is working fine. I have a simple rule that is being executed in a stateless KieSession, no process or whatsoever. I expect the rule to validate basic information and to add information about the fired validations to a global variable. In the example I am testing I just modify a global variable to see if it works, but for some reason I never get a result from

问题 I am using drools with scala in apache spark. In order for KIE to know to look at my private nexus repository for the compiled rules, I am attempting to set the system property: "kie.maven.settings.custom" to a custom settings.xml file which is included in the working directory of the jar file. I am attempting to set this system property at run time, but am having mixed results. Here is my code to set "kie.maven.settings.custom" val userDir = System.getProperty("user.dir") val customPath =

问题 I have created a custom WorkItem with some parameters, which I have registered in WorkDefinitions.wid file. Then in Business Process I also create Variable Definitions for the entire Process and reference those from WD.wid of my custom WorkItem to those created in BP. WorkItem execute the code, which takes those parameters from the form after starting the process. For this purpose I use getParameter()- method; It looks as follows: public void executeWorkItem(WorkItem workItem, WorkItemManager

问题 I want to add a new rule-file (or modify an already existing one) to an existing KieSession dynamically at runtime. I found an answer regarding this and tried the solution mentioned there, but got a runtime exception. The code used is as follows: Driver.java : package app1; import java.io.FileInputStream; import java.io.FileNotFoundException; import org.kie.api.KieBase; import org.kie.api.KieServices; import org.kie.api.builder.KieBuilder; import org.kie.api.builder.KieFileSystem; import org

问题 I am trying to create two independent groups of rules in Drools 6.5 and I can't figure out what's the usecase for the ruleflow-group and agenda-group strategies. They both seem similar. 回答1: Reading the documentation ... 2.6.4. RuleFowGroup and AgendaGroups are merged These two groups have been merged and now RuleFlowGroup's behave the same as AgendaGroups. The get methods have been left, for deprecation reasons, but both return the same underlying data. When jBPM activates a group it now

问题 I'm working with drools engine in the construction of an alert system. we need to execute a method of a @Service instantiated by Spring Framework on the actions of the rule (RHS), when the conditions are met. What would be the way to get the @service instance created by Spring Framework to be used by the action (RHS) of the Drools rule? I have followed the following indications: Using the form import function ( Rule1.drl ). This solution does not work because the class is instantiated in

问题 The "User Guide" for Drools 6 states that a camel endpoint for drools shall be in the below format: <to uri="kie:{1}/{2}" /> where {1} : Execution Node identifier that is registered in the CamelContext {2} : Knowledge Session identifier that was registered in the Execution Node with identifier {1} Doubt # 1 : If the sessions are created before the endpoints are built, how the incremental changes in kmodule will be picked up by the sessions created before?
