Sharing transaction with AbstractRoutingDataSource

I've a problem very close to this one Sharing a transaction while using AbstractRoutingDataSource to switch datasources but I'm not able to solve using the accepted answer. I've a transactional method who have to write the same entity into two different datasource in transactional mode. When transaction commit I've a

Internal Exception: java.sql.SQLIntegrityConstraintViolationException: ORA-00001: unique constraint (VETO_PROD.SYS_C0013988) violated

This is my Transalctional method:

@Override
@Transactional(propagation = Propagation.REQUIRES_NEW)
public ContactTypeJson definisciNuovaContactType(String descrizione) throws Exception {
    String functionCode = RandomStringUtils.randomAlphanumeric(5).toUpperCase();
    LOGGER.debug("Ho generato la functionCode[" + functionCode + "]");
    while (!isContactTypeAvailable(functionCode) || !notificatorService.isFunctionCodeAvailable(functionCode)) {
        LOGGER.debug("La functionCode[" + functionCode + "] e' gia' in utilizzo, genero una nuova...");
        functionCode = RandomStringUtils.randomAlphanumeric(5).toUpperCase();
        LOGGER.debug("...la nuova functionCode generata e' [" + functionCode + "]");
    }
    ContactType contactType = new ContactType();
    contactType.setName(functionCode);
    contactType.setDescription(descrizione);

    notificatorService.insertNewFunction(functionCode, descrizione);
    entityManagerFRVP0.flush();
    entityManagerFRVP0.clear();
    VetrinaContextHolder.setTargetDataSource(VetrinaToolConstants.FRVP_DATASOURCE);
    entityManagerFRVP0.persist(contactType);
    entityManagerFRVP0.flush();
    entityManagerFRVP0.clear();
    VetrinaContextHolder.setTargetDataSource(VetrinaToolConstants.PWVP_DATASOURCE);
    ContactType contactType1 = new ContactType();
    contactType1.setName(functionCode);
    contactType1.setDescription(descrizione);
    entityManagerFRVP0.persist(contactType1);
    VetrinaContextHolder.clearTargetDataSource();
    ContactTypeToJsonConverter converter = new ContactTypeToJsonConverter();
    return converter.convert(contactType);
}

This is the JPA log:

I'm using WebLogic 10.3.5 with XA datasources and org.springframework.transaction.jta.WebLogicJtaTransactionManager

Any idea?

You are violating a unique constraint. I assume you have one defined on the Contact name, so you cannot insert two contacts with the same name.

Trying to switch the connection under a DataSource on the fly seems like a very, very, bad idea. Instead you should have two persistence units, one going to one database, and one going to the other.

You may also want to investigate EclipseLink's data partitioning, or composite persistence units.
