        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
