Example: WSDL File 

 

The diagrams below illustrate components of a WSDL file. A WSDL file requires both the Web service interface and the access description. These areas are handled separately because they are defined at different times: the Web service interface is defined and supplied by SAP; while the access description is dependent on specific company data and is therefore created at a later time.

 

Figure 1: Web Service Interface (IDL)

1.       Data type and structure description (XML schema)

2.       Name of the message

3.       Name of the port type (definition of the interface for input/output message)

 

Figure 2: Access Description (Technical Information for Communication)

1.       Binding: Connection between the interface and the structure of the message (SOAP) and additional communication data if necessary (user, password, etc.)

2.       Service: Specification of the message recipient by URL
