Hi,
I'm trying to develop a web application using jBPM5 integrating with Tomcat7, Oracle10. I could able to start tomcat server and execute code snippet successfully after integration.
But while opening "Process Overview" under "Console", I'm getting below exception,

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 in tomcat path?]
set JBPM_DIRECTORY=-Djbpm.console.directory=C:/jbpm-installer/sample/evaluation/src/main/resources
my code snippet:
KnowledgeBase kbase;
try {
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("Evaluation.bpmn"), ResourceType.BPMN2);
kbase = kbuilder.newKnowledgeBase();
System.out.println("Process flow started ");
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);
System.out.println("Process Id : " + ksession.getId());
logger.close();
} catch (Exception e) {
System.out.println("Exception occurred : ");
e.printStackTrace();
}
}
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 be really greatfull. Please let me know if you need any information.
Thanks,
