Can anyone tell me how to get a process/package from Guvnor and run it from a java app using the demo setup?

I have installed jbpm via the JBPM 5.4 full installer. I have taken the ScriptTask.bpmn from jbpm-examples and successfully put it in the Guvnor. I have added a Model Pojo and was able to build the package inside the default package. I have even created a snapshot.

Guvnor lists these URLS:
| URL for package documentation: | | http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST/documentation.pdf |  http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/clear.cache.gif  (http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/clear.cache.gif) |
 |

 |

Additionally it has this link  http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST Download binary package
Which is to:  http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST

Now I have my main java app:

  package org.jbpm.examples.quickstarts;import java.util.HashMap;import java.util.Map;import org.drools.KnowledgeBase;import org.drools.agent.KnowledgeAgent;import org.drools.agent.KnowledgeAgentConfiguration;import org.drools.agent.KnowledgeAgentFactory;import org.drools.io.Resource;import org.drools.io.ResourceFactory;import org.drools.runtime.StatefulKnowledgeSession;public class HelloRunner {public static final void main(String[] args) {        try {            // load up the knowledge base            KnowledgeBase kbase = readKnowledgeBase();            StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();            Map<String, Object> params = new HashMap<String, Object>();            Person p = new Person("Krisv");            params.put("person", p);            ksession.startProcess("com.sample.script", params);        } catch (Throwable t) {            t.printStackTrace();        }    }    private static KnowledgeBase readKnowledgeBase() throws Exception {        KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration();        KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("testKAgent", aconf);        String fileName = " http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/binary http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/binary";        Resource newUrlResource = ResourceFactory.newUrlResource(fileName);        kagent.applyChangeSet(newUrlResource);        return kagent.getKnowledgeBase();    }}


I have also tried the URL:  http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST

But I keep getting this error:

java.lang.RuntimeException: Unable to parse ChangeSet

I've read various posts about removing authentication and/or putting in the username/password.

I am running the demo stuff, so my understanding is there is no authentication.

So how do I specify a username/password?

I've read something about putting the password in a changeset.xml, but haven't figured out how to do that either...

Thanks!
