If you want a simple way to call a CORBA server from an excel spreadsheet or a VB program you'll find good examples here. What you will not find is any vendor-specific information (it is only 318 pages) or any discussion of Java. Since it is likely that the need for COM/CORBA integration is in legacy systems the exclusive use of C++ and Visual Basic examples is understandable.
Of course, this subject is mind-numbingly dull, but if you absolutely have to do it you'll be finished faster using the patterns described here.
