CPP11 — Potential interop. problem in CORBA 2.3: pseudo-operation marshalling

  • Key: CPP11-135
  • Legacy Issue Number: 2338
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: Existing CORBA 2.2 compatible CORBA clients will fail when invoking
    the non_existent pseudo-operation with a compliant CORBA 2.3 server.
    We have observed this problem in practice with at least one other
    commercial Java ORB, who changed from the Corba 2.2 marshalling to the
    Corba 2.3 marshalling when they changed the version of their product,
    thereby breaking our existing customer"s code.

    Section (p. 15-31) of ptc/98-12-04 CORBA 2.3a defines the CDR
    marshalling for pseudo-operation non_existent in Object
    pseudo-interface to be _non_existent. The spec is worded in such a way
    that it implies that this marshalling applies for all GIOP clients,
    not just GIOP 1.2 client

    However, p. 13-23 of the CORBA 2.2 specification defines the mapping
    of the same pseudo-operation as _not_existent.
