Web Services Invocation Framework (WSIF) is an Application Programming Interface (API) for invoking Web Services Definition Language (WSDL) -described Web services.

WSIF currently provides developers with a standard interface for working with representations of any Web service as an alternative to working directly with a SOAP API. In the WSIF architecture, services are invoked by using WSDL documents. WSIF works with services regardless of how they were implemented or where they reside. Services may be invoked dynamically and without generating stubs. alphaWorks has also started a WSIF FAQ.
