I agree with you. 

Others post here answered about actually existing Ada ORB, and that's OK.
But original laurent's demand was about standart. If Ada ORB do not stick to
the latest CORBA version, it will cause interoperability problems, and will
be also interpreted as a further Ada influence loss.

As Volkert said, for a company involved in big systems, this may lead to Ada
drop (and exceptionnaly with an andisputable reason).

Maybe need we just that ORB vendors set our minds at rest by reaffirming
their commitment in Ada for CORBA, as do by Jean-Claude in this thread.

It may be useful to point our here that similar threads are ongoing in
the comp.object.corba newsgroup.  Victor Giddings of Objective Interface
System posted there some responses to the issues mentioned above.

FYI, I've included the most relevant below.

I always cringe a little when I see statements like this, even if it the
fault of the OMG in part. The fact is that IDL does not change very
often, so the mapping for CORBA 2.3 is equally useful for 3.0, etc. The
work of updating is more often adding a new operation to CORBA.Object or
something like that, or clarifying the specification of existing features
of the mapping. In fact, anything more major would be outside of the
scope of what an RTF (REVISION Task Force) is allowed to do. Case in
point was value types, which required a new RFP.

This is correct. We are working to have an update to meet the 3-week
deadline for the London meeting (due Monday!). Status can be tracked at

You can also refer to my Ada Letters article of five or six years ago,
before I left MITRE. (I can't recall the specific issue, but could look it
up for you). I've also done a more recent article for the COTS Journal (V
3, No. 5, May 2001), but it is more an advocacy article than a tutorial.

You might be surprised at the range of application our Ada product has been
used in. This includes an ocean-going yacht

applications http://www.llnl.gov/nif/, ...

That said, it wouldn't hurt to *see* a bit more Ada related news from
CORBA vendors, both in this newsgroup and elsewhere.

I hope this helps.

Thank you.
As i understand it, the job is ongoing. This is reassuring.

Thanks Lionel.

Indeed my question is the current status of the mapping.

I must apologize for having started this troll but at least one CORBA
tool vendor is now on-line :) We had the advertising part about their
technology, we are now waiting for an answer about the mapping :))
