WSDL bindings

The WSDL binding document defines the protocol details for operations and messages defined by a particular portType. The WSDL binding document is equivalent to a tModel or service interface as published to a UDDI registry. You can generate a monolithic WSDL document that contains all WSDL elements, or a separate WSDL binding document.

The WSDL binding document is a concrete protocol and data format specification for a particular port type. The binding information contains the protocol name, the invocation style, a service ID and the encoding for each operation.

The following WSDL binding document is based on the StockQuoteService Sample.

<?xml version="1.0" encoding="UTF-8"?>
<definitions name="StockQuoteServiceBinding"
targetNamespace="http:///"
    xmlns="http://schemas.xmlsoap.org/wsdl/"
    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:tns="http:///">
    <import location="StockQuoteService.wsdl"
namespace="http:///"/>

  <!--   The mapping to the actual transport protocol names is  
   -->
  <!--   performed in the binding, the next part of the service 
   -->
  <!--   interface file.  StockQuoteServiceSOAPBinding is the SOAP  
   -->
  <!--   binding for the port type.  The binding describes      
   -->
  <!--   which run-time protocol is supported by the service    
   -->
  <!--   provider and contains protocol configuration
information.  -->
