Re: [rules-users] Eval0Invoker : java.lang.NullPointerException

Hi Manstis, I am now getting "RuntimeException" in this code if (builder.hasErrors()) { throw new RuntimeException(builder.getErrors() .toString()); } in my "createKnowledgeBase" method. Can you please let me know what is wrong in this. I have tried what you have said. Thanks, Venkat. -- View this message in context: http://drools.46999.n3.nabble.com/Eval0Invoker-java-lang-NullPointerExcep... Sent from the Drools: User forum mailing list archive at Nabble.com.
