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

[Todd Pagni]

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

processInstanceByteArray, startDate, state, OPTLOCK) values (?, ?, ?, ?,

workItemByteArray=? where workItemId=? and OPTLOCK=?

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();

 

 

Thanks,
Todd
