          Yeah.. Demian nail it:

          you should change this line to make it work

          ksession.getWorkItemManager().registerWorkItemHandler("Email", new EmailWorkItemHandler());

          To match with your process definition

          <task id="_7" name="envio email" tns:taskName="Email" >

            Thanks, I change to ksession.getWorkItemManager().registerWorkItemHandler("Notification", new EmailWorkItemHandler()); and then works.


            Now I am facing another problem, I need to get information of Person in HumanTask 2, I am using this code:


            public Object getTaskContentInput(TaskSummary taskSum) {

                                System.out.println( "======>Entra a ver getTaskContentInput" );

                                try {

                                          BlockingGetTaskResponseHandler handlerT = new BlockingGetTaskResponseHandler();

                                          client.getTask(taskSum.getId(), handlerT);

                                          Task task2 = handlerT.getTask();

                                          TaskData taskData = task2.getTaskData();

                                          BlockingGetContentResponseHandler handlerC = new BlockingGetContentResponseHandler();

                                          client.getContent(taskData.getDocumentContentId(), handlerC);

                                          Content content = handlerC.getContent();


                                          ByteArrayInputStream bais = new ByteArrayInputStream(



                                          ObjectInputStream is = new ObjectInputStream(bais);

                                          Object obj = null;


                                          while ( (obj = is.readObject()) != null ) {

                                                    return obj;



                                } catch (Exception e) {

                                          System.err.print("There was an error reading task input...");




                                return null;




                      public String imprimirTareasConsola( ){

                                HumanTaskClientMina htk = new HumanTaskClientMina();

                                User u= new User("operator");

                                System.out.println( "======>Operador" );

                                List<TaskSummary> t = htk.getAssignedTasks( u );

                                if( t!= null && t.size() >0  ){

                                          Object xx= htk.getTaskContentInput(t.get( 0 ));


                                          if(  xx != null ){

                                                    System.out.println( "===> Class name en content:   " + xx.getClass().getName());

                                                    if( xx instanceof Persona ){

                                                              System.out.println( "==00> Id en content type " + ((Persona)xx).getId() );

                                                    } else if( xx instanceof String ){

                                                              System.out.println( "==00> name type " + (String)xx);


                                                    System.out.println( "===> cerrando Class name en content:   "  );

                                          } else {

                                                    System.out.println( "==> El content es null "  );




                                return null;



            Always the object returned is String, do you have any ideas how can I get the object modified in previus task.

              As Esteban suggested, could you please put this question as anwered and open a new one? Then it is easier for other people to find solutions to problems.
