Spring+Hibernate - LazyInitializationException

[Petr Gola]

Zdravim,

mam nasledujici klientsky kod komunikujici se spring aplikacni vrstvou
(pomoci Spring's HTTP Invoking).

public class MyTest {
 public static void main(String[] args) {
   System.out.println(args[0]);
   XmlBeanFactory beanFactory = new XmlBeanFactory(new
FileSystemResource(args[0]));
   IStockItemService service = (IStockItemService)
beanFactory.getBean("myservice");

   System.out.println("find item by id 5:");
   StockItem item = service.findStockItemById(5);
   String str = null;
   str = ""+item.getId();
//    str += item.getDescription();
//    str += ""+item.getPrice();
   System.out.println(str);

   System.out.println("added item:");
   System.out.println(service.saveNewStockItem(new StockItem("Ahoj",29)));

   System.out.println("all items:");
   List list = service.getStockItemList(null);
   for (Object o : list) System.out.println(o);
 }
}

takhle probehne vse v poradku. Ale pokud se snazim zavolat metody
objektu item getDescription() ci getPrice(), vyskoci nasledujici
chybova hlaska:

find item by id 5:
