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 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
