To view the discussion, visit: https://community.jboss.org/message/779569#779569 -------------------------------------------------------------- Human tasks are added through the default.session.template property file that is baked into console server.  You can override this using your own session.template file, which you need to put in an appropriate location (JBoss conf directory I think?). Human tasks need the knowledge session injected, so they added this functionality.  You can add your own human task implementations this way too. The latest implementation to look at is AsyncHornetQHTWorkItemHandler or AsyncMinaHTWorkItemHandler.  They keep deprecating classes so it is hard to keep up.  These use the AsyncGenericHTWorkItemHandler and AbstractHTWorkItemHandler in its type hierarchy.  Once you get what they are doing, you can write a similar one that suits your needs. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/779569#779569] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]

To view the discussion, visit: https://community.jboss.org/message/779578#779578 -------------------------------------------------------------- default.session.template is in console-server code in src/main/resources.  It looks like this: new SessionTemplate().{      businessKey = "jbpm/consolesession",     imported = false,     persistenceUnit = "org.jbpm.persistence.jpa",     properties = ["drools.processInstanceManagerFactory":"org.jbpm.persistence.processinstance.JPAProcessInstanceManagerFactory",                   "drools.processSignalManagerFactory" : "org.jbpm.persistence.processinstance.JPASignalManagerFactory"                      ],     workItemHandlers = ["Human Task" : "new org.jbpm.process.workitem.wsht.AsyncHornetQHTWorkItemHandler(\"jbpmConsoleHTHandler\", taskClient, ksession, org.jbpm.task.utils.OnErrorAction.LOG)",                         "Service Task" : "new org.jbpm.process.workitem.bpmn2.ServiceTaskHandler(ksession)"],     eventListeners = ["new org.jbpm.process.audit.JPAWorkingMemoryDbLogger(ksession)",                       "new org.jbpm.integration.console.listeners.TriggerRulesEventListener(ksession)"  ] }; You won't find a session.template unless you create one to override this. The session template is loaded by the MVELSingleSessionManager.  The code is like this:             InputStream templateFile = PropertyLoader.getStreamForConfigFile("/session.template", defaultSessionTemplate); So it loads the property from the classpath - you just have to pick a place on the classpath :) . We gave up with this approach as we have dozens of human type tasks and didn't want to configure them all here, and we wrote our own SessionManager, but it is up to you. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/779578#779578] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]

We give it our own so we can add them programmatically rather than using the config file.  Our session manager does what the MVEL one does but doesn't use a template, it adds the task handlers in code.     @SuppressWarnings("unchecked")     public static SessionManager newSessionManager(KnowledgeBase kbase) {         String sessionManager = System.getProperty("jbpm.session.manager");         if (sessionManager == null) {             return new MVELSingleSessionManager(kbase);         }         SessionManager sessionManagerInstance = null;         try {             // build session manager based on given class             Class<SessionManager> sessionManagerClass = (Class<SessionManager>) Class.forName(sessionManager);             Constructor<SessionManager> c = sessionManagerClass.getConstructor(KnowledgeBase.class);             sessionManagerInstance = c.newInstance(kbase);         } catch (Exception e) {             throw new RuntimeException("Cannot create SessionManager from class " + sessionManager, e);         }         return sessionManagerInstance;     } -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/779582#779582] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
