To use the XWSCLientProvider and XWSServerProvider in an upgraded Application Server , you must modify the deployment descriptors of the applications that use these providers, to refer to XWSClientProvider and XWSServerProvider.
The deployment decriptors that you must change are sun-web.xml and sun-ejb-jar.xml. The Upgrade Tool logs a message in the upgrade log if it finds ClientProvider and ServerProvider in the sun-web.xml or sun-ejb-jar.xml.
