What info does the work item contain that the task itself does not?
Basically, the idea would be to put all data that the task needs
(directly) as the content of the task ("Content" parameter), so the
client can access it.

Thanks for the info. I was hoping there was a way to get the work
item
via mina. We have a client application that is communicating with
the
TaskServer via mina and it would be nice if you could easily get a
work
item that is associated with a task instead of creating a separate
knowledgesession.

I guess first you have to get hold of the "workitemid" from the task
data i.e. task.getTaskData().getWorkItemId().
a) Create a "Command" class which implements
GenericCommand<WorkItem>
b) Implement the method "public WorkItem execute(Context
context)"
c) Based on the workitem id ( set this value in your command
object
- constructor/setter) - get hold of the WorkItemInfo object through
the
entity manager and then its workItem ----- something like this
StatefulKnowledgeSession ksession =
((KnowledgeCommandContext)
context).getStatefulKnowledgesession();
if (workItemId==null) {
return null;
}
EntityManager em = (EntityManager)
ksession.getEnvironment().get(EnvironmentName.ENTITY_MANAGER);
WorkItemInfo workItemInfo =
em.find(WorkItemInfo.class, workItemId);
if(workItemInfo==null){
return null;
}else{
return workItemInfo.getWorkItem();
}
d) Then call the execute method on the
StatefulKnowledgeSession -
which should execute the above Command object and that returns you
the
WorkItem object.

>From the Mina client, how do you get a work item associated with a
human
task?
I see the Task.getTaskData(), but I don't see any easy way to get
the
work item as I need the work item inparameters from the mina client
side.
Thanks,
Todd
