[rules-users] Human Task Question on Mina client / server

[Vijay K Pandey]

Instead of "Approve" it should be "Human Task" in the below code

wm.registerWorkItemHandler("Approve", approveTask);

Starting the server first does not fix the issue.   I still see the following error in the log also: [STDERR] Could not find work item handler for Human Task

You need to start the Mina server before starting the process

I am creating a human task in a flow, but I am unable to get the human task in the Mina client.  Should items that enter a humanTaskNode go into the task table in addition to the workItemInfo table?  Do I need to do anything to get the work item set as a potential owner for Administrator so it is returned to the Mina client?

I running drools 5.0.1 in JBoss:


1.       Create the human task node in the flow:


       addActionStep(factory, 3).joinNode(4).type(Join.TYPE_XOR).done().humanTaskNode(5)
        .name("Approve")
        .actorId("Administrator")
        .taskName("Approve")
        .comment("hi")
        .content("random content")


2.       Start the flow process (after this step I a row in the workItemInfo table):



      StatefulKnowledgeSession ksession = km.getSession(kb);



      WSHumanTaskHandler approveTask = new WSHumanTaskHandler();





      /*  Setup workitemmanager here? */

            org.drools.runtime.process.WorkItemManager wm =  ksession.getWorkItemManager();



            wm.registerWorkItemHandler("Approve", approveTask);







        ksession.setGlobal("entity", e);



        ksession.startProcess(DuckFlowBuilder.PROCESS_NAME);



        return ksession;



See the following in the log after this step:
14:37:15,349 INFO  [STDOUT] Hibernate: insert into SessionInfo (dirty, lastModificationDate, rulesByteArray, startDate) values (?, ?, ?, ?)
14:37:15,364 INFO  [STDOUT] Hibernate: insert into ProcessInstanceInfo (lastModificationDate, lastReadDate, processId, processInstanceByteArray, startDate, state, OPTLOCK) values (?, ?, ?, ?, ?, ?, ?)

14:37:15,364 INFO  [STDOUT] Hibernate: update SessionInfo set dirty=?, lastModificationDate=?, rulesByteArray=?, startDate=? where id=?



3.       Start the mina server (don't see anything in the task table)

  EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.drools.task");
     taskService = new TaskService(emf,SystemEventListenerFactory.getSystemEventListener())
     server = new MinaTaskServer( taskService );
        Thread thread = new Thread( server );
        thread.start();
        Thread.sleep( 500 );
        System.out.println("Server started ...");


4.       Run the mina client (no results returned)
           BlockingTaskSummaryResponseHandler summaryHandler =
           new BlockingTaskSummaryResponseHandler()
           client.getTasksAssignedAsPotentialOwner("Administrator", "en-UK",summaryHandler);

           List<TaskSummary> tasks = summaryHandler.getResults();

Todd
