To retieve tasks when user tasks are created using Jdeveloper BPELDesigner

Question

I am trying to get the list of tasks which are created using Jdeveloper BPel designer.
I have used the following code :
Locator loc = new Locator("default","bpel");
          IWorklistService taskService = (IWorklistService)loc.lookupService(IWorklistService.SERVICE_NAME);
ITask[] tasks = taskService.listTasksByAssignee("rekha");
if(tasks!=null){
for (int j = 0; j < tasks.length; j++) {
ITask thisTask = tasks[j];
out.println("Task Title " + thisTask.getTitle() +"Assignee:"+thisTask.getAssignee()+"$$$$"+"\n");
but its not returning any tests.
But the same code works for the tasks which are created through sample bpel processes which are provided by oracle which uses TaskManager service.
But the Jdeveloper bpel designer user task creates service which is TaskActionHandler..
please help me how can I get the List of tasks for a particular user for this problem
Please help me ............

There is sample code that is supposed to do this here: http://www.codeguru.com/cpp/sample_chapter/article.php/c10789__12/
I have tried using the login-style task retrieval with the oracle.tip.pc packages - this works logging in as, for example, fkafka.
Working Code:
IWorklistContext ctx = wlSvc.authenticateUser("fkafka", "welcome");
Map filterMap = new HashMap();
filterMap.put(IWorklistService.FILTER_TYPE_TASK_FILTER,
IWorklistService.TASK_FILTER_MY);
filterMap.put(IWorklistService.FILTER_TYPE_STATUS_FILTER, IWorklistService.STATUS_FILTER_ASSIGNED);
String keywords = "";
java.util.List tasks = wlSvc.getWorklistTasks(ctx, keywords, filterMap, IWorklistService.SORT_FIELD_TASK_TITLE, IWorklistService.SORT_ORDER_ASCENDING);
Using the sample code and retrieving tasks with
ITask[] tasks = worklist.listTasksByAssignee("fkafka");
returns nothing, however.
(&lt;h1>&lt;%= tasks.length %> tasks waiting for approval&lt;/h1>
Prints: ' 0 tasks...' )
I notice that the JDeveloper generated JSPs use the oracle.tip.pc packages - seeing as I'm deploying to the same BPEL server I guess I don't need to worry about the other methods of access (i.e. remote) so hopefully I can manage my workflow app with the oracle.tip.pc packages only.
