    JBPM workIteamHandler registration

    dsagar1234

      Hello All,

       

      I had created domain specific service mentioned on one of JBPM article.When I run this as standalone java programme it works fine.I wanted to resister it with jbpm console,so changed the default.session.properties  as below

       

      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)","Notification" : "new org.jbpm.process.workitem.bpmn2.NotificationWorkItemHandler()"],

                             

          eventListeners = ["new org.jbpm.process.audit.JPAWorkingMemoryDbLogger(ksession)",

                            "new org.jbpm.integration.console.listeners.TriggerRulesEventListener(ksession)"  ]

      };

       

      But I am getting exception as org.drools.WorkItemHandlerNotFoundException: Could not find work item handler for Notification.

      it looks like it doesnt get NotificationWorkItemHandler class,so i tried to put in it server lib,i tried to deploy it as jar and finally i put it in package where other workitemHandler were.,but doesnt seem to be working.

      Any ideas......

       

      Doesit it because GWT CONSOLE SERVER is trying to restore session from database and i had not register workitemHandler at that time.

      If yes then how to register workIteam handler,because then it will be difficult to register new workItemHandler later once we create session.

          your jar file must be placed inside console-server.war/WEB-INF/lib so it can be found and initialized properly.

           

          Please note that you should not change the default.session.template file but create a copy of it in jboss.config.dir (which is by default jboss_home/standalone/configuration) and name that file session.template. More can be found in documentation.
