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: | |
URL for package source: | |
URL for package binary: | |
URL for running tests: | |
Change Set: | |
POJO Model: | |
Additionally it has this link Download binary package
Which is to: 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"; 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
But I keep getting this error:

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!
