Pure CORBA

Chapter 21. CORBA System Exceptions

CORBA provides a set of exceptions that can be raised in the course of any operation invocation without having to be declared in IDL. These are called system exceptions.

The standard system exceptions are defined by a set of categories that should be understood by any CORBA-compliant ORB.

System exceptions are transmitted across the network in a format defined by the General Inter-ORB Protocol (GIOP—see Chapter 14, “Internet Inter-ORB Protocol”). The content of a system exception is defined by the struct shown in Listing 21.1.
