The Web Services Invocation Framework (WSIF) is provided as a stand-alone JAR file named wsif.jar. The JAR file contains the core WSIF classes, and the Java, EJB, SOAP over HTTP and SOAP over JMS providers. Additional providers are packaged as separate JAR files.
When you install WebSphere Application Server, the wsif.jar file is put on the WebSphere or Java Virtual Machine (JVM) class path.
WSIF requires no further configuration. WSIF is a thin abstraction layer between application code and the relevant invocation infrastructure. For specific information on other aspects of managing your WSIF system, see the following topics:
