Hello,

I am trying to set up a simple Drools (6.0.1.Final) application that pulls a kmodule from an external jar that is installed in the local Maven repository. Unfortunately when my code executes the newKieContainer method it crashes with a NullPointerException.

Here is my code...

KieServices kieServices = KieServices.Factory.get();

ReleaseId releaseId = kieServices.newReleaseId("com.mycompany", "mymodule", "1.0-SNAPSHOT");

KieContainer kContainer = kieServices.newKieContainer(releaseId);

And here is the output I get...

[pool-1-thread-1] INFO com.ning.http.client.providers.netty.NettyAsyncHttpProvider - Number of application's worked threads is 16

[pool-3-thread-1] INFO com.ning.http.client.providers.netty.NettyAsyncHttpProvider - Number of application's worked threads is 16

The module has the following dependencies listed in the pom.xml.

I have tried searching for help on this but am unable to find anything related. Any help here is appreciated.

Thanks!
