[jboss-user] [EJB 3.0] - Re: Retrieve retrieve Entity Class mapping from jboss

[florian79]

I created a statless Sessionbean as followed:


  | @Stateless
  | public class BaseSession implements BaseSessionRemote, BaseSessionLocal
  | {
  | 
  |     @Resource SessionContext context;
  |     @PersistenceContext(unitName="myName") private EntityManager entityManager;
  | 
  |     public Map<String,EntityPersister> getAllClassMetadata()
  |     {
  | 	Map<String,EntityPersister> metadata = null;
  | 	try
  | 	{
  | 	    HibernateEntityManager hibernateEntityManager = (HibernateEntityManager)entityManager.getDelegate();
  | 	    metadata = hibernateEntityManager.getSession().getSessionFactory().getAllClassMetadata();
  | 	}
  | 	catch(ClassCastException e)
  | 	{
  | 	    LoggerImpl.getInstance().log(Logger.iLOGG_ERROR, this, e);
  | 	    metadata = new HashMap<String,EntityPersister>();
  | 	}
  | 	return metadata;
  |     }
  | }
  | 
  | 


and then iterate over all maped entities:




  | 	Map m = myPortalSession.getEntityManager().getAllClassMetadata();
  | 	Set<Map.Entry> s = m.entrySet();
  | 	for (Map.Entry e : s)
  | 	{
  | 	    System.out.println(e.getKey() + "--->" + e.getValue());
  | 	}
  |
