"binding" - Binding Definition Element

This section describes 'binding', a definition element that defines a binding for operations defined in a port type to a communication protocol and a message transmission format.

"binding" is a top level element of a WSDL 1.1 document. "binding" is used to define a binding with one or multiple given operations being bound to communication protocol with extensibility elements from WSDL 1.1 extensions. The syntax of "binding" looks like this:

  <wsdl:binding name="nmtoken1" type="qname">
    ... extensibility elements from WSDL 1.1 extension ...
    <wsdl:operation name="nmtoken2">
      ... extensibility elements from WSDL 1.1 extension ...
      <wsdl:input name="nmtoken3">
         ... extensibility elements from WSDL 1.1 extension ...
      </wsdl:input>
      <wsdl:output name="nmtoken4">
         ... extensibility elements from WSDL 1.1 extension ...
      </wsdl:output>
      <wsdl:fault name="nmtoken5">
         ... extensibility elements from WSDL 1.1 extension ...
      </wsdl:fault>
    </wsdl:operation>
  </wsdl:binding>

Notes on the "binding" element:

Here is an example of "binding" element:

  <wsdl:binding name="helloBinding" type="hy:helloPortType">
    <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="Hello">
      <soap:operation
        soapAction="http://www.herongyang.com/Service/Hello"/>
      <wsdl:input name="helloInput">
        <soap:body use="literal"/>
      </wsdl:input>
      <wsdl:output name="helloOutput">
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
