WSIF architecture

A diagram depicting the Web Services Invocation Framework (WSIF) architecture, and a description of each of the major components of the architecture.

The Web Services Invocation Framework (WSIF) architecture is shown in the figure.

The WSIF architecture, showing a Web service being invoked by loading a WSDL document, creating a WSIF service, using the service to get a WSIF operation, then invoking the target Web service by providing the WSIF operation with the name of the target service operation, and the message that it needs.
The components of this architecture include:
WSDL document
The Web service WSDL document contains the location of the Web service. The binding document defines the protocol and format for operations and messages defined by a particular portType.
WSIF service
The WSIFService interface is responsible for generating an instance of the WSIFOperation interface to use for a particular invocation of a service operation. For more information, see the WSIFService interface topic.
WSIF operation
The run-time representation of an operation, called WSIFOperation is responsible for invoking a service based on a particular binding. For more information, see the WSIFOperation interface topic.
WSIF provider
A WSIF provider is an implementation of a WSDL binding that can run a WSDL operation through a binding-specific protocol. WSIF includes SOAP providers, JMS providers, Java providers and EJB providers. For more information, see Linking a WSIF service to the underlying implementation of the service.
