Hibernate prelevare anche gli oggetti figli

[Mitele]

Salve a tutti,
ricordo da molto lontano che per caricare anche i figli di un oggetto bisogna mettere un attibuto lazy o eager .... Qualcuno sa dirmi come fare??

formazioni: Error performing load command
org.hibernate.exception.SQLGrammarException: could not load an entity: [POJO.Computerdevice#1]
	at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:67)
	at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43)

Dove va messo Eage? Forse nel reverse engineering?

eppure ho rifatto la query nel modo piu semplice possibile ottenendo la stessa eccezione:

Exception in thread "main" org.hibernate.exception.SQLGrammarException: could not load an entity: [POJO.Computerdevice#1]

 Query query = conn.createSQLQuery(
             "select * from esecuzione")
             .addEntity(Esecuzione.class);
           
          
            List result = query.list();
            
            
       return result;
