Hibernate version 3.1, Dec 12, 2005
Java version "1.4.2_10"
App Server JRUN 4.0

I have an EJB with method in it and a DAO with 1 method also. When the DAO calls session.save() it throws an exception "save is not valid without active transaction" (stacktrace further down).

1) Hibernate initialized using
static {
try {
sessionFactory = new Configuration().configure().
buildSessionFactory();
} catch (Throwable ex) {
throw new ExceptionInInitializerError(ex);
}
}
2) Remote EJB has 1 method.
3) EJB method has a trans-attribute of "Required"
4) EJB calls DAO using this method
public void createEvent(Event event) {
EventDAOIF dao = new EventDAOImpl();
dao.create(event);
}
5) DAO Code is
public void create(Event event) {
Session session = HibernateUtil.getSessionFactory().
getCurrentSession();
session.save(event);
}

Mapping documents:
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.datasource">com.int.datasource</property>
<property name="hibernate.transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property>
<property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JRun4TransactionManagerLookup</property>
<property name="hibernate.session_factory_name">SessionFactory</property>
<property name="hibernate.current_session_context_class">jta</property>
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="current_session_context_class">thread</property>
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<property name="show_sql">true</property>
<mapping resource="com/iw/integrate/data/event/Event.hbm.xml"/>
<mapping resource="com/iw/integrate/data/person/Person.hbm.xml"/>
</session-factory>
</hibernate-configuration>

Code between sessionFactory.openSession() and session.close():
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.save(event);

I have spent 2 days reading up the relevant tutorials on hibernate, searching over the web for that particular error message and generally EJB-Hibernate interaction and I was unable to find any solution to my problem. I also tried "How do I use Hibernate in an EJB 2.1 session bean?" in Miscellaneous FAQs. I also read "How To Ask For Help" twice just in case I missed something obvious. So please believe me when I say I tried several avenues before posting. Any help is appreciated.

Thanks

what about
session.beginTransaction();

session.getTransaction().commit();

Regards Sebastian

should be


or as mentioned in the JavaDocs for ThreadLocalSessionContext,

rajasaur :
If you look at my post, you will see that that is what I have set the property to <property name="current_session_context_class">jta</property>

LaLiLuna ::
Maybe my understanding is incorrect, but is not the EJB responsible for starting and commiting transaction since I set the attribute to "Required" in ejb-jar.xml ? I was also under the impression that the Session will atomatically associate itself wth the transaction created by the container when a call is made to a method to the EJB.

If you look at Section "11.2.2. Using JTA" in the online tutorial

http://www.hibernate.org/hib_docs/v3/re ... tions.html

It clearly shows that in the case of CMT, I should not have to call openTransaction()

Is my understanding incorrect ?

Thanks in advance

rajasaur ::
My apologies.

There is a typo in my original post. The line with "Thread" is not in my configuration file. I must have pasted it accidently.

You have hibernate.current_session_context_class set to jta and
current_session_context_class set to "thread". Im not sure if the earlier property(hibernate.current_session_context_class) is even considered. You need to change the value of current_session_Context_class from "thread" to "jta".

Hi,

What is the difference between using "thread" and "jta"?

Thank you.
