Re: Spring Autowiring + Hibernate = Security Exception

This looks like the same issue as this one:

My web app makes use of Google Cloud SQL.
It works perfectly locally, using mvn gae:run (mave gae plugin) on
local mysql db.

Here's some of my xml spring context config:

<bean id="mySessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
               <property name="dataSource" ref="myDataSource" />
               <property name="annotatedClasses">
                       <list>
                               <value>it.trew.prove.model.beans.Scadenza</value>
                               <value>it.trew.prove.model.beans.Fornitore</value>
                               <value>it.trew.prove.model.beans.Societa</value>
                       </list>
               </property>
               <property name="hibernateProperties">
                       <props>
                               <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</
prop>
                               <prop key="hibernate.show_sql">true</prop>
                               <prop key="hibernate.hbm2ddl.auto">create</prop>
                       </props>
               </property>
       </bean>

And here's my generic DAO.java:



@Component
public class Dao {

   @Resource(name = "mySessionFactory")
   private SessionFactory sessionFactory;

   @SuppressWarnings("unchecked")
       public <T> T save(final T o){
       return (T) sessionFactory.getCurrentSession().save(o);
   }

   public void delete(final Object object){
       sessionFactory.getCurrentSession().delete(object);
   }

   @SuppressWarnings("unchecked")
       public <T> T get(final Class<T> type, final Long id){
       return (T) sessionFactory.getCurrentSession().get(type, id);
   }

   @SuppressWarnings("unchecked")
       public <T> T merge(final T o)   {
       return (T) sessionFactory.getCurrentSession().merge(o);
   }

   public <T> void saveOrUpdate(final T o){
       sessionFactory.getCurrentSession().saveOrUpdate(o);
   }

   @SuppressWarnings("unchecked")
       public <T> List<T> getAll(final Class<T> type) {
       final Session session = sessionFactory.getCurrentSession();
       final Criteria crit = session.createCriteria(type);
       return crit.list();
   }
}


And one of my services:

@Service
@Transactional
public class ScadenzaService {

       private Dao scadenzaDao;
       private SocietaService societaService;

       public void salvaScadenza(Scadenza scadenza) {
               scadenza.setDataInserimento(new Date());
               scadenza.setSocieta(societaService.getSocietaCorrente());
               scadenzaDao.save(scadenza);
       }

       public List<Scadenza> tutteLeScadenze() {
               return scadenzaDao.getAll(Scadenza.class);
       }

       @Autowired
       public void setScadenzaDao(Dao scadenzaDao) {
               this.scadenzaDao = scadenzaDao;
       }

       @Autowired
       public void setSocietaService(SocietaService societaService) {
               this.societaService = societaService;
       }
}

What do you think? Why in local works and not in GAE?
