[rules-users] java.lang.RuntimeException: Unable to instance KieServices

[kurrent93]

Hi

I am trying to get started with Drools 6x, and in eclipse, I have created a
Drools project, which creates the boilerplate code to run a simple drl.

I have the drools runtime installed via Eclipse.

Yet, when I try to run the following, I get  the following error:

java.lang.ExceptionInInitializerError
	at com.sample.DroolsTest.main(DroolsTest.java:15)
