问题 I want to call a Java function from a Utils class which calls a JPA Repository method for retrieving a custom object. I want to call this function from a Drools decision table. Now, this simple function is giving Null Pointer Exception and I have already lost several hours on this. I have a Functions field declared under "Import" section of the decision table, and there I have declared a simple function which calls this particular Java function with the repository method. Can you provide me

问题 I am trying to get JPAKnowledgeService work with my Spring Boot application. For this I have followed the instructions from here.

问题 I'm new to Drools, so pardon me if the question seems stupid. I have written rules for values which have ranges in numeric format. Can someone please let me know how can we write rules for alphanumeric ranges. Below is the rule I've written for numeric ranges. claim.Medicalcare.get("CLM07-00").Value >= $1, claim.Medicalcare.get("CLM07-01").Value <= $2 The above rule is for values ranging 1-9. I need to write a rule which has values G0129-G2341,M9867,99234-99350. I'm writting these rules in

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"")

问题 I'm trying to implement a jBPM6 project containing both processes and rules. One thing I would like to achieve (if it is possible) is to develop a separate artifact containing only the rules definitions, and then referencing this jar into the processes' project via maven, being able to execute the rules from my processes. I implemented this solution, but when I execute one of the process that uses the rules none of the rules is fired. To verify that there were no implementation problems I put

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 =
