Which statement is accurate about configuring a SOAP web service client in Mule?

• A. It requires the service contract in WSDL format.
• B. It can similarly be configured using a REST description.
• C. It does not require any contract.
• D. It uses a WADL file to configure the SOAP client.

Answer: (A)

SOAP clients in Mule rely on the service contract written as a WSDL. The WSDL describes what operations are available, the structure of the input and output messages, the data types involved, and how the service is bound to a particular endpoint. When you configure a SOAP web service client in Mule, importing the WSDL lets the tool generate the proper client stubs and automatically set up the request envelopes, headers, and payloads to match the contract. A REST description or WADL is meant for REST services, not SOAP, and there isn’t a contract-free way to correctly form SOAP requests. So the statement that the SOAP client configuration requires the service contract in WSDL format is the accurate one.
