Enterprise beans are Java objects operating in a sophisticated runtime environment which includes an ORB. If the enterprise bean is to make outbound IIOP calls to remote CORBA objects (without using RMI-IIOP) it is strongly recommended that the application make use of the existing ORB instance. If the enterprise bean creates a new ORB instance using the new operator, CICS cannot propagate the existing transaction and security context under which the bean is running to method requests on this new ORB.
