after a while i got this working.

@Stateless
| @Name("building")
| public class BuildingListAction implements BuildingList,Serializable{
|  
|  private static final long serialVersionUID = 1L;
|  
|  private List<BuildingType> objects;
|  Map<String,BuildingType> buildingsMap;
|  
|  @PersistenceContext
|   EntityManager em;
|  
|  public Map<String,BuildingType> getBuildings()
|  {
|    objects = em.createQuery("select b from BuildingType b")
|      .setHint("org.hibernate.cacheable", true)
|      .getResultList();
|
|   Map<String,BuildingType> results = new TreeMap<String,BuildingType>();
|  
|   for (BuildingType buildingtype: objects)
|   {
|    results.put(buildingtype.getName(),buildingtype);
|   }
|  
|   buildingsMap = results;
|    
|    return buildingsMap;
|  }
|
|   public Converter getConverter()
|   {
|      return new BuildingTypeConverter(objects);
|   }
| }


im not familiar with ejb but this obviously leads to a query every time the method getBuildings() is called. My goal is to load the objects only once and then return a list every time the methos is called. Can somone help me with that or point me to an example or tutorial which describes that?

regards,
hasc
