Albert,

Until now, you're arguments sounded sensible, even if I didn't
agree with all of them. :-(

The winner of the DCOM-CORBA war was HTTP because it delivered
a killer app - sharing of information - and because a certain
company made sure CORBA wasn't widely deployed. The influence
of industry politics has had a massive impact on what people
use, e.g. SGML partly died because powerful IT companies which
owned the word processing market 10 years ago "pre-announced"
support for SGML in their products (which never really arrived, BTW)
so the actual SGML products never mainstreamed. It's rather
ironic to see one of those same companies pushing XML with
such vigor now. Is it doing it because XML is *that* much
better than SGML? Or could it be because Java now exists?

SOAP and XML are 'simple' technologies *because* of the
success of the Web and because software engineers are
familar with HTML, CSS, etc. SOAP will have it uses and
they will be really important ones (e.g. B2B) but it
certainly isn't the answer to life, the universe and everything.
People will also use it inside the firewall because,
once you have a hammer, everything looks like a nail.
Eventually, most designers will pick more appropriate
solutions, e.g. CORBA with pub-sub, JCA+JMS or EAI tools.
