The way you invoke a Web service from an application program (or
from a wrapper program) depends upon whether or not you are using the Web
services assistant to deploy your application.
Invoking a Web service from other applications
A service requester application that is not deployed with the Web
services assistant links to program DFHPIRT to invoke a Web service. The request
message and response message, and other information that CICS uses to
process the request are held in a set of containers.
