JAX-RS using exception mappers
Is InvalidDataException getting wrapped in a PersistenceException? Maybe you could do something like the following:
@Provider
public class PersistenceMapper implements ExceptionMapper<PersistenceException> {
@Override
public Response toResponse(PersistenceException arg0) {
if(arg0.getCause() instanceof InvalidDataException) {
return Response.status(Response.Status.BAD_REQUEST).build();
} else {
...
}
}
}
