CORBA/TAO vs XML

[Dave]

Hi,

I heard that CORBA/TAO is not only overkilled for most of client/server
appplication, it also has serious compatibility problem with its older
version. CORBA/TAO tend to be a general purpose C++ library, but it ends
up not useful for specific application. It seems that use other specific
libraries like botan/cryptopp, regexx, sockets, xml libraries could
build a much more reliable application and thus easier to maintain in
the long run.

I m wondering whether this is truth in most of client/server/system
application that written in C++. Can anyone also suggest few good C++
libraires that I can replace current ACE/TAO libraries?

Thanks

XML is the way to go.

Try out Xerces C++ based XML parser library:
http://xml.apache.org/xerces-c/

TinyXML would be another option:
http://sourceforge.net/projects/tinyxml/

For client/server appplications C++ is not the right 'environment'. Not
because the language is inappropriate (quite contrary) but because
there is no C++ 'community' that is interested in and builds usable
frameworks for this tasks. Just switch to the Java platform with its
abundant offerings in this area.

Java has been the platform I m looking into. More over, I m building
embedded application, Java platform will take considerable capacity in
the base system. I could probably build a C++ server and Java clients.

That's pretty good. Both projects are painlessly installed in my system. :)

I would think that SOUP is worth to look into for building a
client/server applicatoin. Does it have java version?

????? What specific application? CORBA is used in countless (many
mission-critical) applications in banking, finace, science (etc etc etc).

Well, for simple, non-mission critical applications not under heavy
load, you could just pass xml messages over the wire (the SOAP way), or
use sockets and implement your own marshalling technology. Good luck!

CORBA is designed to solve one problem: communication between objects
over the wire written in different languages. And it solves this very
well. The J2EE technology has borrowed heavily from CORBA, and even uses
the same protocol, the IIOP.

Whats wrong with ACE/TAO? There is OmniORB
(http://omniorb.sourceforge.net) which is really efficient and stable,
there are commercial offerings from IONA (ORBIX and ORBACUS), and many
others.

There is also ICE (http://www.zeroc.com/) which is a better and simpler
CORBA.

Anyway, distributed computing is NOT easy, and the different frameworks
reflect that. Even SOAP, which started out as a simple solution to
distributed objects, are now reinventing the wheels you find in CORBA,
out of sheer necessity. Soon, SOAP and similar XML messaging
technologies end up as complex and "unmaintaniable" as CORBA.

Thanks for your explaination. It definitely solved my concerns of using
ACE/TAO in a client/server project.
