Linking a WSIF service to the underlying implementation of the service
A Web Services Invocation Framework (WSIF) service is linked to the underlying service through a WSIF provider. A provider is an implementation of a Web Services Description Language (WSDL) binding that can run a WSDL operation through a binding-specific protocol. Providers implement the interface between the WSIF API and the implementation of a service.
About 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™ Platform, Enterprise Edition (Java EE) programming model to use Java EE 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:
