Hi,
I am trying to use transactions (JTA) and JPA with Aries blueprint but I did
not manage to make it work.
I don't want to use XA datasource because I only access a single database. So
In my JPA persistence.xml file I have something like :
<persistence-unit name="test">
<jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jdbc/testdb)</jta-data-source>
...
My blueprint.xml contains :
<bean id="personService"
class="test.service.impl.PersonServiceImpl">
<tx:transaction method="*" value="Required"/>
<jpa:context property="entityManager" unitname="test"/>
</bean>
I have written a test to check transaction's rollback, using a transactional
method like the following :
public class PersonServiceImpl implements PersonService {
...
public void createPerson(Person person) {
entityManager.persist(person);
entityManager.flush();
throw new RuntimeException("exception");
}
}
I was expecting that the created person would not be written to the database
after calling "createPerson" because of the Exception, but it is not the case !
The person object is persisted in the database.
It appears that the underlying JDBC Connection has an autocommit property set
to "true", so rollback is impossible. I thought transaction manager would take
care of JDBC connection autocommit, but it is not the case.
The result is the same with OpenJPA and Hibernate.
Am I missing something related to JTA ?
Thanks for your help.
