Web Services Invocation Framework

Web Services Invocation Framework (WSIF):

The Web Services Invocation Framework (WSIF) is a Java API for invoking Web servicesn without directly accessing a SOAP API, such as AXIS. WSIF provides the same kind of functionality that JAXP does for Web parsing. A WSIF interface can be used on any WDSL-compatible Web service, regardless of the SOAP or WSDL version or implementation that the service was originally created under. For example, moving from Apache SOAP classes to Apache AXIS classes does not require any changes to application code if the WSIF interface is employed. The WSIF implementation code can be found at http://ws.apache.org/wsif. WSIF implementation code is also integrated into some application development tools, such as IBM’s WebSphere application developer and Web Services Toolkit.
