<class name="com.dss.core.i18n.models.I18NDescriptionModel" entity-name="PDM" table="DB_PDM_I18NDESCRIPTION" lazy="true">

Code between sessionFactory.openSession() and session.close():


if (actionType.equals(CommonInfo.DELETE)) {
i18NDescriptionModel.setIsDeleted(CommonInfo.IS_DELETED);
getDataAccessor().update(entityName, i18NDescriptionModel);
}

and update method is

public void update(String entityName, Object object) throws DataAccessException {
Session session = null;
try {
session = getHibernateSession();
session.update(entityName, object);
session.flush();
} catch (HibernateException ex) {
handleHibernateException(ex);
} finally {
// to avoid NonUniqueObjectExceptions and to control the size of first level (session) cache
session.clear();
if (isAllowCreate()) {
// only if the session was created as in the secondary data accessor, release it
if (session != null) {
SessionFactoryUtils.releaseSession(session, getSessionFactory());
}
}
}
}
