JCA provides a standard client programming model for accessing EIS
services. The CCI exposes a simple programming model based on
Web Service Invocation Framework (WSIF) API. The language used to describe
the meta-information of an EIS is WSDL, which is the standard for describing
the services offered by a specific EIS instance and how you access them. The
following table maps the data relevant to performing an operation between
JCA and WSDL:
