at the same EJB

I have a facade (Stateless) and a DAO (stateless)

@Stateless
@Local(HotelService.class)
@Remote(HotelService.class)
public class HotelServiceBean implements HotelService {


@EJB
private HotelDao hotelDao;

public List<Hotel> findAllHotels() {
return hotelDao.findAllHotels();
}

public Hotel saveHotel(Hotel newHotel) {
Hotel hotel = hotelDao.saveHotel(newHotel);
String test = null;
if(test == null){
throw new RuntimeException();
}
return hotel;
}

}


As you can see after the dao save the record i throw an exception , but the record was save to the DB and roll back was not executed.

Hey Avihai,

Does that mean transaction was not supported by MySQL? I believe it uses InnoDB for transaction management. Thanks for posting the solution.

Its mean that you need to create the Tables or the storage engine InnoDB and not ISAM in case you need transaction
 
It is sorta covered in the JavaRanch Style Guide.
