Bhaskaran Venkataraman [https://community.jboss.org/people/bhaskarven] created the discussion "Task Service Issue" To view the discussion, visit: https://community.jboss.org/message/739284#739284 -------------------------------------------------------------- I am trying to understand the Human Task Service through an example. I found useful information regarding the communication between the Task Client and the Task Service in the User Guide. TaskClient client = new TaskClient(new MinaTaskClientConnector("client 1",     new MinaTaskClientHandler(SystemEventListenerFactory.getSystemEventListener()))); client.connect("127.0.0.1", 9123); // adding a task BlockingAddTaskResponseHandler addTaskResponseHandler = new BlockingAddTaskResponseHandler(); Task task = ...; client.addTask( task, null, addTaskResponseHandler ); long taskId = addTaskResponseHandler.getTaskId();         // getting tasks for user "bobba" BlockingTaskSummaryResponseHandler taskSummaryResponseHandler =     new BlockingTaskSummaryResponseHandler(); client.getTasksAssignedAsPotentialOwner("bobba", "en-UK", taskSummaryResponseHandler); List<TaskSummary> tasks = taskSummaryResponseHandler.getResults(); // starting a task BlockingTaskOperationResponseHandler responseHandler =     new BlockingTaskOperationResponseHandler(); client.start( taskId, "bobba", responseHandler ); responseHandler.waitTillDone(1000); // completing a task responseHandler = new BlockingTaskOperationResponseHandler(); client.complete( taskId, "bobba".getId(), null, responseHandler ); responseHandler.waitTillDone(1000); But in the evaluation sample code there is only a specific type of HumanTaskHandler (HornetQ) registered listening on a particular port and then the process is started. I mean we have not instantiated any Task Client and we are not doing any manual processing of the human tasks. It is not clear what happens behind the scenes. If we have to use the task client and handle all the actions mentioned above how do we communicate with the JBPM Engine. After the process is started by the engine and when a human task is encountered how does it come to execute our code. If there is an example to illustrate the sequence it will help. Thanks for your help. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/739284#739284] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
