Make minor backward-compatible changes to your Web services (IBM developerWorks)

[Posted December 1, 2004 by cook]

Russell Butek covers web services versioning issues on IBM developerWorks. "Web services versioning doesn't really exist. To achieve new versions of a service, you have to create a new set of WSDL/XSD files with new namespaces, essentially creating a new Web service. That's a rather drastic solution. There are some changes you can make to an existing set of WSDL and XSD files that are backward compatible so that you can evolve your service, to a limited degree, without the drastic measure of creating a new one."
