I'm having a problem where
the addition of spring's transaction management to an application causes Hibernate to throw
the following error:
org.hibernate.HibernateException: A collection with cascade="all-delete-orphan" was no longer referenced by

I'm using Spring 2.5 and annotations to implement this management. Here is
the class containing
the saveNewReportCriteria method (which, as can be seen by
the stack trace, is causing
the error)
@Transactional(
propagation = Propagation.REQUIRED,
isolation = Isolation.DEFAULT,
readOnly = false)
public class HibernateReportCriteriaDao implements ReportCriteriaDao{
private HibernateTemplate hibernateTemplate;
public Integer saveNewReportCriteria(ReportCriteriaBean reportCriteria) {
hibernateTemplate.save(reportCriteria);
List<Integer> maxIdList = hibernateTemplate.find("SELECT max(id) from ReportCriteriaBean");
logger.info("ID of newly saved list is: " + maxIdList.get(0));
return maxIdList.get(0);
}
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
}
Then I added
the following sections to my configuration files to tell spring that I am using annotation driven transaction management:
<bean id="actgDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/actg" />
<property name="resourceRef" value="true" />
</bean>
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="actgDataSource" />
</bean>
<tx:annotation-driven/>
I'm pretty sure that
the de-referencing error is being caused due to
the proxy class that Spring AOP creates and uses in order to handle transaction management, but I have no idea how I'd go about fixing it.
