Getting a user task list by assignee...

Question

Hello,
I had many problems trying to get a user task list from a java file. I found a way.
I do it this way because the IWorklistService class return cero tasks with any WhereCondition... please if any one found a proper way to do this, please let me know.
I use nanoxml library.
public static ArrayList queryWorklistServiceI(ArrayList users){ 
// Lookup the worklist service.
IWorklistService worklist =
(IWorklistService)locator.lookupService( IWorklistService.SERVICE_NAME );
try
WhereCondition cond = new WhereCondition();
cond.append("title like '%TaskActionHandler'").append("and").append(WhereConditionHelper.whereInstancesOpen());
IInstanceHandle[] i = locator.listInstances(cond);
ArrayList tareas = new ArrayList();
for(int j=0; j<i.length;j++){
IXMLParser xmlParser = XMLParserFactory.createDefaultXMLParser();
IXMLReader xmlReader = StdXMLReader.stringReader(i[j].getAuditTrail());
xmlParser.setReader(xmlReader);
IXMLElement xml_e = (IXMLElement) xmlParser.parse();
Vector children = xml_e.getChildren();
IXMLElement task = ((IXMLElement)children.get(4)).getFirstChildNamed("details");
IXMLParser xmlParser_task = XMLParserFactory.createDefaultXMLParser();
IXMLReader xmlReader_task = StdXMLReader.stringReader(task.getContent());
xmlParser_task.setReader(xmlReader_task);
IXMLElement xml_task = (IXMLElement) xmlParser_task.parse();
xml_task = xml_task.getFirstChildNamed("part").getFirstChildNamed("task");
String asignado = "";
asignado = xml_task.getFirstChildNamed("assigneeUsers").getContent();
if(asignado==null){
asignado = xml_task.getFirstChildNamed("assigneeGroups").getContent();
boolean b = false;
for(int k=0;k<users.size()&&!b;k++){
if(((String)users.get(k)).equals(asignado))
if(b){
String id = xml_task.getFirstChildNamed("instanceId").getContent();
String titulo = xml_task.getFirstChildNamed("title").getContent();
String estado = xml_task.getFirstChildNamed("state").getContent();
String modificado = (xml_task.getFirstChildNamed("modifyDate").getContent()).substring(0,16);
String tarea_id = xml_task.getFirstChildNamed("taskId").getContent();
Vector datos = xml_task.getFirstChildNamed("payload").getFirstChildNamed("Datos").getChildren();
ArrayList datos_array = new ArrayList();
for(int k=0;k<datos.size();k++){
IXMLElement dato = (IXMLElement)datos.get(k);
Dato d = new Dato(dato.getFirstChildNamed("Nombre").getContent(),dato.getFirstChildNamed("Valor").getContent(),false,"");
datos_array.add(d);
Tarea t = new Tarea(id,titulo,estado,asignado,modificado,tarea_id,datos_array);
tareas.add(t);
return tareas;
} catch (Exception e){System.out.println(e);}
return null;
