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

[Todd Pagni]

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] Entity name: Mallardes, Step: 3

	14:37:15,364 INFO  [STDOUT] Hibernate: insert into WorkItemInfo (creationDate, name, processInstanceId, state, OPTLOCK, workItemByteArray) values (?, ?, ?, ?, ?, ?)

	14:37:15,364 ERROR [STDERR] Could not find work item handler for Human Task

	14:37:15,364 INFO  [STDOUT] Hibernate: update ProcessInstanceInfo set lastModificationDate=?, lastReadDate=?, processId=?, processInstanceByteArray=?, startDate=?, state=?, OPTLOCK=? where processInstanceId=? and OPTLOCK=?

	14:37:15,364 INFO  [STDOUT] Hibernate: update WorkItemInfo set creationDate=?, name=?, processInstanceId=?, state=?, OPTLOCK=?, 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
