How to get Rule Definition from DRL File in BRMS

Is there a way to get a rule definition from a DRL file in JBOSS BRMS using rest or java API? I have a Kie server where my container is loaded, can I get the rule file definition from the container using API or REST call.

We are using 6.5.0.Final-redhat-2 version of KIE and 6.4.0.GA version for BRMS

Solution

  • There is no KieServer API to return a DRL resource as of today. If you have the DRL file or the kjar containing the file, you can use the parser API to retrieve the rue definition:

    Here are some test cases with examples of how to use the parser to inspect rules:
