<h4><a name="wswsifovr">An overview of WSIF</A></h4>
|
|
|
|
<p>WSIF provides a Java API for invoking Web services, independent of the format of the service or the transport protocol through which it is called. It addresses all of the issues identified in the goals of WSIF.</p>
|
|
|
|
<p>WSIF provides these features:</p>
|
|
|
|
<ul><li>It has an API that provides binding-independent access to any Web service.</li>
|
|
<li>It is closely based on WSDL, so it can call any service that can be described in WSDL.</li>
|
|
<li>It allows stubless (completely dynamic) call of a Web service.</li>
|
|
<li>You can plug a new or updated implementation of a binding into WSIF at run time.</li>
|
|
<li>You can defer the choice of a binding until run time.</li>
|
|
</ul>
|
|
<p>WSIF is designed to work both in an unmanaged environment (stand-alone) and inside a managed container. You can use JNDI to find the WSIF service, or else read in the WSDL definition.</p>
|
