WSIF and WSDL

There is a close relationship between the metadata-based Web Services Invocation Framework (WSIF) and the evolving semantics of Web Services Description Language (WSDL).

In WSDL, a service is defined in three distinct sections:

Currently in WSDL, each port has one and only one binding, and each binding has a single portType. But (more importantly) each service (portType) can have multiple ports, each of which represents an alternative location and binding for accessing that service.

The Web Services Invocation Framework (WSIF) follows the semantics of WSDL as much as possible:

As a metadata-based invocation framework, WSIF follows the design of the metadata. As WSDL is extended, WSIF is updated to follow.

The primary type system of WSIF is XML schema. WSIF supports invocation using dynamic proxies, which in turn support Java™ type systems, but when you use the WSIFMessage interface to invoke a Web service through the WSIF API you must populate WSIFMessage objects with data based on the XML schema types as defined in the WSDL document. You should define your object types by a canonical and fixed mapping from schema types into the runtime environment.
