Why? First, one of the great attractions of a distributed object system is precisely that I'm not typically zapping objects about the network, but am rather dealing with the more interesting objects in different address spaces by (remote) reference. So, as an an application developer using corba, I really don't care too much how my corba implementation (as provided by Iona or whomever) does its business (e.g., marshalling). I just care that it does it correctly and, hopefully efficiently. The question then becomes: "does a corba implementation developer (e.g., someone writing orbix at Iona) want to use xml as the underlying representation for the marshalling of objects?" I still think the answer to this question is likely "no." It'll likely be less efficient than other such implementations, and adds little value otherwise. Finally, I'm not convinced that a corba/RPC-style of remote method invocation is typically well suited to web-oriented interactions -- most things on the web can be treated naturally and efficiently as streams. Why add the extra weight (which seems to buy me little) of corba to a domain in which it seems a mis-fit? > Furthermore I am suggesting that by enabling use of web native > protocols > under currently available distributed object systems we can move toward a > better integration of distributed objects and the web. > I certainly share your enthusiasm for a better integration between distributed objects and the web. My experience thus far tells me that layering corba (or some other rpc -like mechanism) on top of more ubiquitous streaming protocols costs a lot and yields little benefit. However, efforts like http-ng offer the promise of such an integration without carrying some of the baggage that might come with trying to shoehorn a big heavy thing like corba on top of something so umm svelte ;-> as http and friends.
