drools-guvnor

问题 I have been trying follow the links and details available to set up a KIE Drools workbench for Drools like https://www.intertech.com/simple-setup-of-drools-kie-workbench-and-kie-server-in-one-wildfly-instance/.

问题 Introduction Drools Guvnor has it's own versioning system, that in production use allows the users of an application to modify the rules and decision tables in order to adapt to change in their business. Yet, the same assets continue to live on the development version control system, where new features to the app are developed. This post is for looking insight/ideas/experience on rule development and deployment when working with Drools rules and Guvnor. Below are some key concepts I've been

问题 Please let me know how to use ".?" (null safe operator) in drools decision table(Spreadsheet). Attached my spreadsheet, where for mdcl object I need to add null safe operator. Please let me know if I need to add additional information, as I'm new to Drools. 回答1: The null-safe operator in Drools is !. , not .? - see the documentation. You can use it inside decision tables just as you would when writing rules. In your example, change the condition from mdcl.MDCL_Health.get("MDCL").Value to mdcl

问题 I'm building a rules project using Guvnor. In one of my DSL, I've the follow "consequence" statement for wrong operations: [when]Error "{message}"=throw new Exception( "{message}" ); If I use the DSL rule, writing all the rule with DSL sentences, it works perfectly. However, using the Guided Editor, this doesn't work and the validation says anything like that: [Error: unable to resolve method using strict-mode: org.drools.spi.KnowledgeHelper.throw()] [Near : {... throw new Exception( " ...

问题 Attached is my decision table, where in I'm using sv2.SV202_CompMedProcedId.get("SV202-02") several times in my condition. Is there any way that we can create an alias for sv2.SV202_CompMedProcedId.get("SV202-02") (for example, S) and use that alias in my condition instead of using the entire line every time? CONDITION sv2.SV202_CompMedProcedId.get(""SV202-02"").Value >= '70010' && sv2.SV202_CompMedProcedId.get(""SV202-02"").Value <= '76499' || sv2.SV202_CompMedProcedId.get(""SV202-02"")
