    How to load processes from Guvnor Repository?

    mark boletti Newbie

      Hi all !

      I'm looking for a way to load my process from the Guvnor Repository. The process has been created in the defaultPackage and according to the Web designer it's valid.

      Here's how I am trying to load it:

       

      private static KnowledgeBase readKnowledgeBase() throws Exception {

        KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

        kbuilder.add(ResourceFactory.newClassPathResource("sample.bpmn"), ResourceType.BPMN2);

        return kbuilder.newKnowledgeBase();

        }

       

       

        public void startProcess() throws Exception {

        

        KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration();

               KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("admin", aconf);  

               String fileName = "http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST/ChangeSet.xml";

       

               kagent.applyChangeSet(ResourceFactory.newFileResource(fileName));

               KnowledgeBase kbase2 = kagent.getKnowledgeBase();

               StatefulKnowledgeSession ksession2 = kbase2.newStatefulKnowledgeSession();

              

               ProcessInstance process = ksession2.startProcess("defaultPackage.StartWKFlow");

               System.out.println("process "+process.getProcessId()+" " +process.getProcessName());

        // start a new process instance

        ksession.startProcess("com.sample.bpmn.hello",parameters);

        

        }

      Unfortunately I'm unable to retrieve the ProcessInstance as an error "Invaild Process ID" is raised.

      Has anybody knowledge how to solve this problem ?

      thanks

      Mark
