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]* Sep 2, 2011 5:39:07 PM org.apache.mina.filter.logging.LoggingFilter log INFO: CREATED Sep 2, 2011 5:39:07 PM org.apache.mina.filter.logging.LoggingFilter log INFO: OPENED *No properties file: roles.properties found* Sep 2, 2011 5:39:07 PM org.apache.mina.filter.logging.LoggingFilter log INFO: RECEIVED: HeapBuffer[pos=0 lim=178 cap=2048: 00 00 00 AE AC ED 00 05 73 72 01 00 1D 6F 72 67...] Sep 2, 2011 5:39:07 PM org.apache.mina.filter.logging.LoggingFilter log INFO: SENT: HeapBuffer[pos=0 lim=188 cap=256: 00 00 00 B8 AC ED 00 05 73 72 01 00 1D 6F 72 67...] Sep 2, 2011 5:39:07 PM org.apache.mina.filter.logging.LoggingFilter log INFO: SENT: HeapBuffer[pos=0 lim=0 cap=0: empty] *jbpm.console.directory property not found* Sep 2, 2011 5:39:13 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [Resteasy] in context with path [/gwt-console-server] threw exception *org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException: Could not initialize stateful knowledge session: No Persistence provider for EntityManager named org.jbpm.persistence.jpa*     at org.jboss.resteasy.core.SynchronousDispatcher.handleApplicationException(SynchronousDispatcher.java:319)     at org.jboss.resteasy.core.SynchronousDispatcher.handleException(SynchronousDispatcher.java:230)     at org.jboss.resteasy.core.SynchronousDispatcher.handleInvokerException(SynchronousDispatcher.java:206)     at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:360)     at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:173)     at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:93)     at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:68)     at javax.servlet.http.HttpServlet.service(HttpServlet.java:722)     at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:304)     at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210)     ........... 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.
