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:
