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

processInstanceByteArray, startDate, state, OPTLOCK) values

3. Start the mina server (don’t see anything in the task tabl
e)
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
