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 components of this architecture include:
- WSDL document
- The 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.
- WSIF operation
- The runtime representation of an operation, called WSIFOperation is responsible for invoking a service based on a particular binding.
- 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. These providers link the WSIF service to the underlying implementation of the service.
