A Web Services Invocation Framework (WSIF) service is linked to the underlying service through a WSIF provider. A provider is an implementation of a WSDL binding that can run a WSDL operation through a binding-specific protocol. Providers implement the interface between the WSIF API and the actual implementation of a service.
Why and when to perform this task
Providers are pluggable within the WSIF framework, and are registered according to the namespace of the WSDL extension that they implement. Some providers use the Java 2 platform, Enterprise Edition (J2EE) programming model to utilize J2EE services. If a provider is available, but its required class libraries are not, then the provider is disabled.
To use the providers that are supplied with WebSphere Application Server, see the following topics:
