<p><strong>WSIF architecture.</strong>
<br>The WSIF architecture, shows a Web service 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 target service operation's name and the message that it needs.</p>
<p><strong>WSIF provider</strong>
<br>A WSIF provider is an implementation of a WSDL binding that can run a WSDL operation through a binding-specific protocol. WebSphere Application Server - Express includes WSIF providers for SOAP over HTTP, and Java. For more information, see <a href="wswsifprov.htm">Use the WSIF providers</a>.</p>
<p><strong>WSIFOperation</strong></p>
<p>The runtime representation of an operation, called WSIFOperation is responsible for invoking a service based on a particular binding.</p>
<p><strong>WSIFService</strong>
<br>The WSIFService is responsible for generating an instance of WSIFOperation to be used for a particular invocation of a service operation.</p>
<p><strong>WSDL documents</strong>
<br>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.</p>
