Thanks for your answer it helped a bit...

but what is the best Approach to get Task Information for building Remote Task UI? Any Example? Do i have to put all Variables in inputData  or in Content with a Map ?

And the result of

  List<TaskSummary> tasksAssignedAsPotentialOwner = client.getTasksAssignedAsPotentialOwner("admin", "en-UK");

don't show all actual Tasks. In gwt-consol i see actualy even more tasks ( for "admin" ) than in HornetQClient.

SOLUTION: The TaskClient needs a unique Name.

For Test I use now the "Evalution.bpmn"

Now I want to retrieve the Content build a generic UI.

I use the HornetQ TaskService and read the DocumentConten like this:

     List<Task> tasksAssignedAsPotentialOwner = taskManagement.getAssignedTasks("admin");

     Task simpleTask = tasksAssignedAsPotentialOwner.get(0);

     long taskId =  simpleTask.getId();

     assertEquals(Status.Reserved, simpleTask.getTaskData().getStatus());

     taskManagement.start(simpleTask.getId(), "admin");

     simpleTask = taskManagement.getTaskById(taskId);

     assertEquals(Status.InProgress, simpleTask.getTaskData().getStatus());

     Content content = taskManagement.getContent(simpleTask.getTaskData().getDocumentContentId());

     Map<String, Object> contentData = (Map<String, Object>) ContentMarshallerHelper.unmarshall(content.getContent(), null);

     logTaskData(simpleTask);

Now i've got all Data from the "Self-Evaluation" Task. But in Content i can only see the Key : reason - Value : Some Reason.

In the Web View the user have to check some CheckBoxes to give the Task a valid Result. How can I retrieve the Information about the Result Values / Types?

How to retrieve the Values of performance?

I followed that example :

https://community.jboss.org/people/bpmn2user/blog/2011/02/21/jbpm5-example-for-forms-with-variables

It works now. Istead of PreProcess Skript Tasks I used the onEntryAction!
