Hi,

Why not we just exchange plain XML over HTTP?
It's going to be platform independent as well.

As such, can someone please enlighthen me as to
why we use SOAP instead of just plain XML.



Thanks in advance.

That's a fair question. The answer is that doing without SOAP is in fact gaining momentum, and that approach is known as "REST". The http://faq.javaranch.com/java/WebServicesFaq links to many introductory articles on that subject.

James,

SOAP vs. POX vs. REST says -

So if you want security, reliability etc., you need SOAP (or you have to invent your own version of it and convince others to use it too .. good luck). Obviously not every scenario needs all that muscle ...


and

POX/HTTP means exchanging plain old XML documents over HTTP. RESTful POX, i.e. using XML in a RESTful manner, would mean POX is a subset of REST. Many, if not most POX applications don't care about REST very much, though � they'd thus be part of a distinct set of applications.


Regards,
Dan

James,

I work with an enterprise Search product called Autonomy and content management systems for the enterprise in which XML over HTTP is the standard practice.

Dan
