What is WSDL?...
Web Services Description Language
Specification that describes a service’s interface
Similar to CORBA IDL
- Describes the target interface
- But goes beyond what IDL provides
Can be seen as IDL that can handle multiple networking protocols
If service supports multiple protocols
- Client can choose the most appropriate one, dynamically, at run time
Notes:
WSDL (Web Services Description Language) is the specification that describes a service’s interface. WSDL is somewhat similar to the CORBA IDL in that it describes the target interface, but it goes beyond what IDL provides.
WSDL can be seen as IDL that can handle multiple networking protocols. If a client – and the service – support multiple protocols, the client can choose to use the most appropriate protocol, dynamically, at run time.
