Hi there,
I have created sample Spring + JPA app on GAE and everyting works fine
(add/edit) exept remove.
My applicationContext config is :
<context:component-scan base-
package="com.s_sandbox.tutorial.firsr.dao" />
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"
lazy-init="true">
<property name="persistenceUnitName"
value="transactions-optional" /
>
</bean>
<bean name="txManager"
class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory"
ref="entityManagerFactory" />
</bean>
<tx:annotation-driven transaction-manager="txManager" />
And my DAO is :
@Component
public class ContactDAO extends JpaDAO<Long, Contact>{
@Autowired
EntityManagerFactory entityManagerFactory;
@PostConstruct
public void init() {
super.setEntityManagerFactory(entityManagerFactory);
}
}
and
@Transactional(readOnly = true)
public abstract class JpaDAO<K, E> extends JpaDaoSupport {
protected Class<E> entityClass;
@SuppressWarnings("unchecked")
public JpaDAO() {
ParameterizedType genericSuperclass =
(ParameterizedType)
getClass()
.getGenericSuperclass();
this.entityClass = (Class<E>) genericSuperclass
.getActualTypeArguments()[1];
}
@Transactional(readOnly = false, propagation =
Propagation.REQUIRES_NEW)
public void remove(E entity) {
getJpaTemplate().remove(entity);
}
/* Other code */
}
I do not recive any errors. looks like my transactions does not work
but I have not idea why.
