RE: Web Services/SOA (was RE: XML 2004 weblog items?
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).
