Persistence with EJB3 doesn't work

Question

I have a method to save a new object in an EJB bean. This method is called, without error, but nothing changes in the database. I can't understand why.

Here is the code:

@Stateless(name = "Ar", mappedName = "ManagementBean")
public class ManagementBean implements IManagementBeanLocal, IManagementBeanRemote {
...
    @Override
    public int storeRawSms(String raw, String requestUid, String text, String service, boolean correctlyAnalysed, Date receivedTimestamp,
            boolean toBeAnalysed, String phoneNumber) {

        // Get phone number, create if it dosn't exist
        PhoneNumber pn = getOrCreatePhoneNumberPrivate(phoneNumber);

        // Create rawSMS
        RawSms rawSms = new RawSms(raw, requestUid, text, service, correctlyAnalysed, receivedTimestamp, toBeAnalysed, pn);

        // Store and return result
        em.persist(rawSms);
        int result =  rawSms.getId();

        em.flush();
        em.clear();

        return result;
    }

...

And the caller:

@PersistenceContext private EntityManager em; 
... 
int rawSmsIs = bean.storeRawSms(raw, requestUid, message, service, false, new Date(), true, sender);

Do you have an idea?

Answer 1

It seems that your transaction never commited, so try changing transaction management:

@Stateless(name = "Ar", mappedName = "ManagementBean")
@TransactionManagement(TransactionManagementType.BEAN)
public class ManagementBean implements IManagementBeanLocal, IManagementBeanRemote {

      @Resource
      private UserTransaction utx;

      @Override
      public int storeRawSms(..) {

            try {
                  utx.begin();
                  ..
                  em.persist(rawSms);
                  int result =  rawSms.getId();
                  utx.commit();
            }
            catch(Exception ex) {
                  //EXCEPTION HANDLING
                  utx.rollback();
            }
      }
}
