WSDL

The WSDL (Web Services Description Language) file describes the services offered by a server. It contains:

The description of the operations offered by the server, and each operation's input and output messages.
The location of the SOAP server.
Internal connection and protocol details (transport layer, encoding, namespaces, and so on).

A WSDL description is sufficient to provide all the information required to communicate with the SOAP server.

Genero Web Services package provides a tool, fglwsdl, that enables Genero client applications to obtain the WSDL description of a Web Service.
