RE: [xml-dev] Web Services/SOA (was RE: [xml-dev] XML 2004 weblog items?)

["Chiusano Joseph" <chiusano_joseph@bah.com>]

One can also map CORBA to Web Services - in Eric Newcomer's Intro to Web
Services book he discusses a mapping that I roughly recall as follows
(WSDL on left, CORBA on right):

Interface --> Object Class
Operation --> no direct mapping
Message --> Method
Part --> Argument

So for a Purchase Order interface, we would have:

Purchase Order Interface --> Purchase Order Class
getPurchaseOrderStatus message --> getPurchaseOrderStatus method
PurchaseOrderID Part --> PurchaseOrderID Argument

Some of the emerging WS-* specifications also address resources, in a
manner that some say is "CORBA all over again". In particular:
WS-Transfer and OASIS Web Services Resource Framework (WSRF).
