Subject: RE: Initial correlation of ebXML Transport requirements with CORBA services

Well put.

Food 4 thought:

I would add to your comments that in the end, commercial transactions for
over the internet via XML will require functionality that is similar to
almost all of the
already-thought-out CORBA Services, and Java Enterprise semantics; without
an ORB.
If you buy into this thought, the intellect of these problems has already
been spent,
and a logical approach to some of this may be to start with these current
programming models
and collaboration patterns mapped to an ORBless environment.

Hi Rik,

No, there are no plans to convert CCORBA to an XML based mechanism,
but there is already an active move to make it easier to use CORBA
to support XML -- you could do it with what's in CORBA products on
the market today treating XML as an octet string or character string.
However, the new work, the RFP is called XML/value, will do a better
job of it.

This is a major reason I'm participating in the Transport & Packing
group -- XML needs a transport which provides security (encryption,
authentication, non-repudiation and all that good stuff) and also
a transport which provides the two phase commit semantics for
once-and-onnce-only (which will probably be VERY important to
e-commerce as I don't think banks will be too keen on transferring
millions of dollars/euros if there is a chance the transport is
going to lose or possible replicate the transfer ;-).  CORBA has it
now, our specs are open (indeed, we're submitting them to ISO
using their PAS process), and the specs are implemented in
commercially supported products which are on the market.

Information on XML/value is on our web site at
As I said, it's new and the list of companies which have turned in
a Letter of Intent to submit is on this page (there is definite
interest).  We haven't had any submissions yet, but that's not too
surprising as the deadline hasn't passed.  For those interested in
more detail, there's a link to the RFP itself.

On the OMG home page, there is also a pointer to some more info on
XML as it relates to OMG -- http://www.omg.org/xml/

There are two other areas in which we currently use XML:
1. XMI which is an XML based means for texhanging UML models and
   other meta data, and
2. in our component model where descriptors of components are in
However, this isn't the subject of your question.

Hope this helps without being too long.  Glad to answer any further
questions.  Sorry about preaching two phase commit transaction
processing, but I'm a true believer.  It probably won't be the
last time I'll harangue the group on this :-)

Best regards,
