WSDL

16 Nov

The purpose of WSDL is to “describe” your web services. A Web Service is described by a document in XML format, in the XML language known as WSDL (Web Services Description Language). This describes the service in terms of the operations, messages, and bindings that it contains, and may provide a URL at which the service may be called.

The structure of the messages is described using XML Schema (XSD) which is either contained in, or referred to by, the WSDL.The messages sent to, and received from, the web service are all in the form of XML that complies to the schema, and which follows the protocols described by the WSDL, using an XML protocol known as SOAP (for Simple Object Access Protocol).
