I am not familiar with TAO myself, but with Corba in general (I am an
omniORRB fan).
The fact that your java client gets a reference from the TAO name
service suggests that RMI-IIOP is used rather than plain RMI (JRMP).

As Phil Mesnier has stated you can rmic -idl to generate IDL. This
generated very ugly IDL in general, with lots of valuetypes. The problem
might be to use these valuetypes from C++. If your RMI methods use
non-remote objects as parameters or results you need these valuetypes.
If they are anything other that simple things like strings, e.g. your
own objects, or instances of very specific Java classes you have a
problem as you would have to emulate these in C++.
In those cases you might be able to write some wrapper classes in Java
to make access from C++ easier. These wrappe classes could use RMI-IIOP
or Corba. I think the latter option gives you more possibilities.
