Hi there,

I am using Guvnor 5.3.0 war and drools 6.0.0.Beta5 in JBOSS 7. I deployed succesfully I can able to navigate to create business rule from Guvnor screen but I am getting nullpointer exception during invoke   KnowledgeAgentFactory.newKnowledgeAgentConfiguration(). Please help me here.

Guvnor 5.3.0 is deployed in server. drools 6.0.0 is configured in my workspace.

Code: 

import org.kie.internal.KnowledgeBase;

import org.kie.internal.KnowledgeBaseFactory;

import org.kie.internal.agent.KnowledgeAgent;

import org.kie.internal.agent.KnowledgeAgentConfiguration;

import org.kie.internal.agent.KnowledgeAgentFactory;

import org.kie.internal.io.ResourceFactory;

import org.kie.internal.runtime.StatefulKnowledgeSession;

private static KnowledgeBase createKnowledgeBase() {
       
        KnowledgeAgentConfiguration kaconf =
            KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
        // Do not scan directories, just files.
        kaconf.setProperty( "drools.agent.scanDirectories", "false" );
        KnowledgeAgent kagent =
            KnowledgeAgentFactory.newKnowledgeAgent("test agent", kaconf );
        kagent.applyChangeSet( ResourceFactory.newClassPathResource("guvnor-jboss.xml"));
        return kagent.getKnowledgeBase();
     

    }

I can see newKnowledgeBase() setting properties by defult if input parameters are not passed. I feel something need to be configured enviorment.
