Hi !

I have a few entity beans with validation annotations, and I'd like to be able to catch the exceptions thrown by the hibernate validator when something goes wrong.

@Entity
public class Country {

 @Id
 @GeneratedValue( strategy=GenerationType.AUTO )
 private Integer id;

 @NotNull
 @Length(min = 1, max = 255)
 private String name;
}

@Stateless
@Remote(Update.class)
public class UpdateSessionBean implements Serializable, Update {
 public CountryDataBean updateCountry( CountryDataBean bean )
 throws UpdateException {
 Country entity = this.entityManager.find( Country.class, bean.getId() );
 if ( entity == null ) {
 throw new UpdateException( "Country not found" );
 }

 CountryMapper mapper = new CountryMapper();
 mapper.toEntity( bean, entity );

 try {
 entity = this.entityManager.merge( entity );
 }
 catch( InvalidStateException e ) {
 ... do some stuff
 }

 mapper.toDataBean( entity, bean );
 return bean;
 }
}

When I force an error, I get that kind of error message :

19:49:43,158 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator_2] TwoPhaseCoordinator.beforeCompletion - failed for com.arjuna.ats.internal.jta.resources.arjunacore.SynchronizationImple@7cd469

Does anyone have an idea of how I could catch those damned exceptions in my session bean ? Cause it's pretty pointless for me to validate the data if I can't find a way to know that something went wrong :(

I'm using JBoss 4.2.0 !

Best regards,
