you’ll need to write a minimal self contained unit test:
http://docs.jboss.org/drools/release/6.0.1.Final/drools-docs/html/Welcome.html#gettingstarted
You’ll need to submit the test to this module:
https://github.com/droolsjbpm/drools/tree/master/drools-decisiontables/src/test
Lots of programmatic builder tests, to follow as examples here:
https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test/java/org/drools/compiler/integrationtests/KieBuilderTest.java
Also did you try doing it non-programmaticaly first? The non-api way is the preferred and recommended way. The api is there for tooling and stuff that is done purely at runtime.
