The CORBA does all the marshalling and finding the methods to run via IOR
and ORB when used with Java also puts the data returned into an appropriate
data type. Corba goes beyond rpc as you don't need to know where the remote
procedures just what they are called and the Interface definition is known.
Again if it is in Java and written in Bean style it is possible to
interogate the introspection aspect of the class to tell you about itself.

CORBA allows you to encapsulate legacy applications (30 yo COBOL) to appear
as a single access point to other applications (eg Java Applet).
