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;
}
}
The error 500 on Appengine is:

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