The Web Services Invocation Framework (WSIF) architecture is shown in the
figure.
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 Finding
a port factory or service
- 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 WSIF API reference:
Using ports.
- 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 Using the WSIF providers.
