MyFaces Orchestra: How to Integrate with Hibernate ?
Hello list, I'm trying to integrate MyFaces Orchestra with Hibernate
(and Spring 2.5.6), I have already downloaded the example application
from http://code.google.com/p/myfaces-orchestra-goodies/ where an
HibernatePersistentContextFactory is provided, there is also an
example of a DAO that extends the Spring's HibernateDaoSupport class.
I don't like the idea of implement my DAOs extending a Spring class,
so instead I wrote them as the example shown below.
It seems that I'm doing something wrong, because I'm having two kind
of HibernateExceptions at different points of my application, in one
case it's telling that a collection is used in another session, in the
other case that a session is closed.
The application is layered in this way: [conversation score beans] ->
[service layer] -> [dao layer] -> [hibernate]
I can't figure out how HibernatePersistentContextFactory is assigning
the same session to the different DAOs in the dao layer, I think it
isn't happening and that is the cause of the exceptions.
Hope someone can point me in the right direction.
Examples:
@Repository("userDAO")
public class HibernateUserDAO implements UserDAO {
@Autowired(required=true)
private SessionFactory sessionFactory;
public HibernateUserDAO() {}
public Session getSession() {
return sessionFactory.getCurrentSession();
}
public List<UserDto> getAll() {
Session session = getSession();
Query query = session.createQuery("FROM UserDto AS user ORDER BY
user.username ASC");
return (List<UserDto>) query.list();
}
// other methods...
}
@Service("userService")
public class UserServiceImpl implements UserService {
@Autowired(required=true)
private UserDAO userDAO;
@Transactional(readOnly = true)
public List<UserDto> getAll(){
return userDAO.getAll();
}
// other methods...
}
@Component("userAdministrationBean")
@Scope("conversation.access")
@ConversationName("userAdministrationBean")
public class userAdministrationBean {
UserDto currentUser;
@Autowired(required=true)
private UserService userSvc;
public List<UserDto> getAllUsers() {
return this.userSvc.getAll();
}
// other methods...
}
If you are still reading this, this is the interesting part of the
Spring application-context.xml:
<tx:annotation-driven/>
<!-- 3. the "entity manager" manager -->
<bean id="persistentContextConversationInterceptor"
class="org.apache.myfaces.orchestra.conversation.spring.PersistenceContextConversationInterceptor">
<property name="persistenceContextFactory"
ref="persistentContextFactory"/>
</bean>
<!-- 4. conversation - persistence adapter -->
<bean id="persistentContextFactory"
class="my.application.db.HibernatePersistenceContextFactory">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="entityManagerFactory"/>
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation">
<value>classpath:hibernate.cfg.xml</value>
</property>
</bean>
Re: MyFaces Orchestra: How to Integrate with Hibernate ?
Posted by Alejandro Valdez <al...@gmail.com>.
Yes, the classes and methods in the service layer are annotated with
@Transactional.
It seems that it's working now, It seems that the class that need
access to the retrieved objects *must* be annotated with @Component
In my case I had a MainBean that created an AuxBean using new(), the
MainBean was annotated with @Component, but AuxBean was not because I
thought that as it was created inside the MainBean then it should
share the persistence context of the MainBean.
To fix it, I annotated AuxBean with @Component and replaced the new()
in MainBean for an @Autowired.

Are you sure you have the @Transactional around?

Re: MyFaces Orchestra: How to Integrate with Hibernate ?
Posted by Alejandro Valdez <al...@gmail.com>.
I'm sorry to insist (I don't like to beg for help), but I really can't
figure out how Orchestra persistence context works with Hibernate, I'm
just getting LazyInitializationException with the message "could not
initialize proxy - no Session".
Since my first e-mail I've implemented my DAO classes extending
HibernateDaoSupport, but that didn't solve the issue.
I think that there is something wrong with the way the application is
layered (because the service/dao layer beans don't belong to any
conversation):
[conversation scope beans] -> [service layer] -> [dao layer] -> [hibernate]
Or the persistence context feature from Orchestra isn't working.
The (hibernate proxied) objects are correctly retrieved in the
dao/service layers, but LazyInitializationException is thrown when
they are accessed from a conversation scope beans.
Well, hope someone can give me a hand.
PS: Again, I'm sorry to insist.
This is the kind of stack trace that I get:
org.hibernate.LazyInitializationException: could not initialize proxy
- no Session
org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:86)
org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:140)
