Web Services Invocation Framework (WSIF): Enabling Web services

 

Before you begin

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 includes an EJB provider for EJB invocation using Remote Method Invocation over Internet Inter-ORB Protocol (RMI-IIOP). However, for EJB(IIOP)-based Web service invocation you should instead invoke RMI-IIOP Web services using JAX-RPC.

 

Overview

The Web Services Invocation Framework (WSIF) is a WSDL-oriented Java API. You use this API to invoke Web services dynamically, regardless of the service implementation format (for example enterprise bean (EJB)) or the service access mechanism (for example Java Message Service (JMS)).

Using WSIF, one can move away from the usual Web services programming model of working directly with the SOAP APIs, towards a model where you interact with representations of the services. We can therefore work with the same programming model regardless of how the service is implemented and accessed.

If you want to know more about the issues that WSIF addresses, see Goals of WSIF.

If you want to know how WSIF addresses these issues, see An overview of WSIF.

To use WSIF, see the following topics:

• Using WSIF to invoke Web services.

• WSIF system management and administration.

• WSIF API.
