WSDL is the language that UDDI uses. Web services are application components that are designed to support interoperable machine-to-machine interaction over a network. It is an API provided by Java that is used for developing soap web services. Before you generate Web services, consider these issues: WebServicesAssembler places some restrictions on the WSDL that you specify: The WSDL should comply with Web Services-Interoperability (WS-I) Basic Profile 1.0. 4. To generate an Apex class from a WSDL: In the application, from Setup, enter Apex Classes in the Quick Find box, then select Apex Classes.

You might however wonder how the WSDL … 6. WSDL was developed jointly by Microsoft and IBM. This interoperability is gained through a set of XML-based open standards, such as the Web Services Description Language (WSDL), the Simple Object Access Protocol (SOAP), and Universal Description, Discovery, and Integration (UDDI). 3.3 Simple Object Access Protocol (SOAP) page 71. The Web Service Receiver Server Connector supports generation of a WSDL file according to the input and output schema of the AssemblyLine. I will be using SOAPUI (a free open source tool), but you can use whatever tool you like. Architects disagree somewhat on how to start defining Web services using WSDL, particularly if the services aren't written yet. 3.2 Web Services Description Language (WSDL) page 66.
