Abstract:
CORBA has some positive aspects to develop applications, but its communication model is limited to accomplish interactions among clients and enterprise servers on the Web. The technologies of Web Service seem to offer a better answer for developing distributed applications on the Web. The first part of this paper is a discussion about the evolution of CORBA and of Web Services, showing their benefits and limitations. The new solutions provided by the technologies of Web Services (XML, WSDL, UDDI and SOAP) are more adapted for the Web than CORBA. However, these technologies are not sufficient to compose Web Services, which represents a real challenge. Workflow Technology seems to be a better answer for this challenge. The second part of this paper deals with this integration of Workflow technology and Web service that is designed in WEWS. An approach for transaction based on conversation plus optimistic commit protocol is also presented. A comparison of our work and other propositions
is provided too, highlighting similarities and differences.
