An overview of WSIF

The Web Services Invocation Framework (WSIF) provides a Java API for invoking Web services, independent of the format of the service or the transport protocol through which it is invoked. This framework addresses all of the issues identified in the goals of WSIF.

WSIF provides the following features:

  • An API that provides binding-independent access to any Web service.

  • A close relationship with WSDL, so it can invoke any service that one can describe in WSDL.

  • A stubless and completely dynamic invocation of a Web service.

  • The capability to plug a new or updated implementation of a binding into WSIF at run-time.

  • The option to defer the choice of a binding until run-time.

WSIF is designed to work both in an unmanaged environment (stand-alone) and inside a managed container. We can use the Java Naming and Directory Interface (JNDI) to find the WSIF service, or use the location described in the WSDL.

For more conceptual information about WSIF and WSDL, see the following topics:

WSIF supports Internet Protocol V6, and Java API for XML-based Remote Procedure Calls (JAX-RPC) V1.1 for SOAP.
