[EJB 3.0] - Throw an exception dosnt cause to rollback when it is not in
by avihaimar
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 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.

[Beginners Corner] - Re: invoking an EJB over iiop
by HibsMax
Last post on the subject. I have EJB invocation working over IIOP. The key changes I had to make were:
1. add this to client code:
if ( System.getSecurityManager() == null )
| {
| System.setSecurityManager(new RMISecurityManager());
| }
this change enables RMI's to download EJB stubs from a remote server.
2. create a java.security.policy file and include it as a runtime system property:
grant {
| permission java.security.AllPermission;
| };
this allows the client to download files (as well as everything else that AllPermission allows).
3. changed the PROVIDER_URL from iiop://server:3528 to jnp://server:1099. I never found a link to what the PROVIDER_URL should be set for for IIOP so I was guessing. The final guess, which was really a simple reversion, seems to have been the correct one.
Some / all of this may have been obvious to other people but, if not, I hope this helps out others who have similar problems.
Peace, Anders
