WSDL
The Web Services Description Language (WSDL) is an XML-based language for describing Web services and how to access them.
Before a Uniface application can call a Web service (call-out), it needs to import the WSDL file of this Web service using the WSDL Import facility.
When a Uniface service is published as a Web service (call-in), its interface needs to be exported into a WSDL file using the WSDL Export facility.
Binding Styles
A WSDL document can have different binding styles to define the message format and how the service is bound to a protocol. There are four binding styles, each suited to a specific situation. Some styles are compliant with WS-I Basic Profile 1.1 and Simple SOAP Binding Profile 1.0.
All the binding styles are supported by Uniface Web service call-out. For Web service call-in, the default binding style of Uniface WSDL files is the Document/Literal Wrapped style, which is the style best suited to most situations. You can also use the RPC Encoded style.
