Caused by: javax.persistence.TransactionRequiredException: Executing an update/delete query - spring

Question

I'm working on a project using JSpring and JPA/Hibernate. I try to call a native query to update the DB. Here is the error trace:

My DAO Class

private static final Logger logger = Logger.getLogger(daoImpl.class);
#PersistenceContext(unitName="ncrm_extraction")

EntityManager emBpa;
#Transactional
public int UpdateExt(String pk_obj_id_Rem,String Req) {

Query q = emBpa.createNativeQuery(Req);
// q.setParameter("Date", dteTr);

int flag=q.executeUpdate();
return flag;

Answer 1

suppose you modify your DaoImpl as below.
#Modifying(clearAutomatically = true)
#Transactional
public int UpdateExt(String pk_obj_id_Rem,String Req) {
logger.debug("### DAO : Modifier le flag EXT table remise : "+pk_obj_id_Rem );
Query q = emBpa.createNativeQuery(Req);
int flag=q.executeUpdate();
return flag;
}
Hope this helps.
