Hi,
i have want a stateless session bean to serve Objects to a selectItems
component. So far i have adopted a stateful bean from the dvd example to serve
the objects.
the code is the following:
@Stateful
| @Name("building")
| public class BuildingListAction implements BuildingList,Serializable{
|
| private List<BuildingType> buildings;
| Map<String,BuildingType> buildingsMap;
|
| @PersistenceContext
| EntityManager em;
|
|
| @Create
| public void loadData() {
| buildings = em.createQuery("select b from BuildingType b")
| .setHint("org.hibernate.cacheable", true)
| .getResultList();
|
| Map<String,BuildingType> results = new
TreeMap<String,BuildingType>();
|
| for (BuildingType buildingtype: buildings) {
| results.put(buildingtype.getName(),buildingtype);
| }
|
| buildingsMap = results;
| }
|
| public Map<String,BuildingType> getBuildings(){
|
| return buildingsMap;
| }
|
| public Converter getConverter() {
| return new BuildingConverter(buildings);
| }
|
| @Remove @Destroy
| public void destroy() {}
| }
my question is now what is necessary to make this bean a stateless bean. I
stuck at the point where to initialize the list and where to execute the query.
Thanks a lot.
regards,
hasc
