What you'll want to use is the IDL Connector objects, which were build
for this exact scenario. They are part of IDL 6.4 (no extra license
required). Built off the IDL Export Bridge technology, these are basic
COM and Java objects that provide simple access to IDL (Execute
String, Set/Get variables). This is much easier that Callable IDL,
which is difficult to use. So if you can access COM or Java from your
application, you could use this technology.
