Ada and C++ communications using CORBA

Ada and C++ communications using CORBA

[Mike Silburn]

I am investigating the feasibility of re-using legacy Ada applications
with new  C++ developments using CORBA and the Portable Object Adapter
to communicate between the Ada and other areas.

Has  anyone successfully integated Ada with C++ using CORBA?

Regards Mike

Mike,

We've had Ada83 integrated with CORBA for about 4-5 years. Unfortunately,
we had to do it the hard way,
writing our own code generator that wrapped the Ada code into a C++ BOA
ORB environment.

These days there exist a number of Ada95 POA ORBs on the market.
OrbExpress is a good example.

I would suggest that you have a look at AdaBroker, our free software
CORBA tool chain for Ada 95. We provide a POA implementation,and
generation of Delegation packages for easy wrapping of legacy
applications.

I recall a presentation on the National Ignition Facility (I think
that's it's name) that used C++ for GUIs and Ada for the real-time,
important stuff, communicating via CORBA.

Well, the scenario is that the Ada and C++ parts are completely separate. In
your case, this will be C++ clients to an Ada server that wraps the legacy
application(s). So it depends on how well you wrap your legacy apps as a
server. Cheers,

The National Ignition Facility is indeed our name: lasers.llnl.gov/
lasers/nif.html.  We're a  $2Billion Department of Energy project for
laser-driven fusion research.  Located at Livermore National Lab in
California.  Described in the '98 SIGAda.

Our integrated control system is written in Ada and communicates via
CORBA.  But our plan to use C++ for our GUI's has been replaced by Java.

We're getting excellent results using ORBexpress in Ada and Visibroker in
Java.

Hi there, are you folks using Ada just for 
hardware control & real-time stuff, or are
you also using it for calculations & offline
data processing?

Hello,

I can ony agree with this. We have done already 2 successfull projects,
using this configuation.

We're using Ada *by policy* in the integrated control system: all the
systems that operate the equipment.  Real-time controls are encapsulated
in the lowest-level equipment control ("Front-end Processor") computers.
Event-driven operator interfaces (that have Java GUI fronts) run "in the
control room."  Higher-level functions in aid of large-scale integration,
eg experiment planning or system-wide diagnosis, are planned in the same
integrated system (in Ada).

There are of course numerous other software components - project and
business management, configuration databases, the physics models of laser
performance, analysis of experimental data - that already exist or will
be constructed using whatever technology best fits the application.
SQL database interactions and CORBA interfaces open these without overly
constraining our programming technology choices.

Our experimental data - much of it images - are still several years in
future. Thes will be saved in standard file formats (HDF for example) and
will be processed using commercial or academic processing software.
