Hi again,
Hi!
* org.hibernate.HibernateException: No CurrentSessionContext
configured!
The suggested way is to override getSession() to return something
other than sessionFactory.getSession() or set a CurrentSessionContext
in you SessionFactory (recommended). This section in the Hibernate
documentation tells you why and how:
http://docs.jboss.org/hibernate/stable/core/reference/en/html_single/#architecture-current-session.
. I tried with the three available values for property
"hibernate.current_session_context_class", it only works with
value org.hibernate.context.ThreadLocalSessionContext.
However, a new problem
* org.hibernate.HibernateException: createCriteria is not valid
without active transaction

My AppModule already includes the following contribution for decorating
all the DAO services :
@Match("*DAO")
public static <T> T
decorateTransactionally(HibernateTransactionDecorator decorator,
Class<T> serviceInterface,
T delegate,
String serviceId)
{
return decorator.build(serviceInterface, delegate, serviceId);
}
So at this point would require a deeper understanding of tapestry-hibernate.
Greetings,
Antonio
A few changes in BaseHibernateDAO :
- Replaced the import of class org.hibernate.classic.Session with
org.hibernate.Session.
Thanks for pointing me that. I've just fixed this in the Generic
DAO-Hibernate branch. By the way, in the Maven repository, there is an
improved 1.1 version there.
- Add the org.hibernate.Session object as a new paremeter in all the
constructor methods.
- Changes in class BaseHibernateDAO :
Add new field of type org.hibernate.Session, that will be
initialized inside the constructor ( like the SessionFactory does )
Modify the method getSession(), returning the new field
reference
These modifications aren't appropriate to *Generic* DAO-Hibernate, as
they wouldn't work without Tapestry-IoC (for example, when you're
building a desktop application or using Spring), and this package is
meant to be independetly from Tapestry-IoC.
