Re: Instantiating a process in JBPM5

Hi,

 

I'm trying to do a simulator web application using Tomcat7, Oracle10 with the help of JBPM5 demo. As a process I could able to start the tomcat server successfully and could run below code without any issues,

 

        // load up the knowledge base

        KnowledgeBase kbase;

        try {

            KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

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

            kbase = kbuilder.newKnowledgeBase();

            StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

            //KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newThreadedFileLogger(ksession, "test", 1000);

            ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());

            // start a new process instance

            Map<String, Object> params = new HashMap<String, Object>();

            params.put("employee", "krisv");

            params.put("reason", "Yearly performance evaluation");

            ksession.startProcess("com.sample.evaluation", params);

            //logger.close();

        } catch (Exception e) {

            System.out.println("Exception occurred : ");

            e.printStackTrace();

        }

    }

 

 

But while opening "Process Overview" under "Console", but I'm getting below exception, [I have tried the steps mentioned above]

Even in console its reporting about the properties file, I've set the path in Catalina.bat as,  [I'm not sure about roles.properties where to set?]

   set jbpm.console.directory=-Djbpm.console.directory=C:/jbpm-installer/sample/evaluation/src/main/resources

 

 

Also I couldn't able to start "http://localhost:8080/drools-guvnor", do we need any extra configurations other than libraries?

 

 

Your immediate response/help would me really greatfull. Please let me know if you need any information.

 

 

Thanks,

Kishore
