WSDL files
The Web Services Description Language (WSDL) file is an optional XML file generated by ProxyGen and used by the Sonic Web Services Invocation framework to generate a proper SOAP message. It contains information required by programmers of client applications that will call the service. It is a standard component widely used in the industry for development of Web service clients, however the WSDL file generated by ProxyGen is specifically for use with Sonic’s Web Service Invocation and is not appropriate for use with outside clients. WSDL files are stored as resources in Sonic ESB and can be viewed with Sonic Workbench. For more information on the WSDL files generated for the OpenEdge Adapter for Sonic ESB and how Web service clients must use them, see OpenEdge Development: Web Services.
