Is web services going to replace corba stuff for legacy integration?

Are there any real success story of corba?

Thanks for your input.

I feel that future application that need interoperability will be written in Web service.

Check this link to read how web services relate to CORBA:

What I want to look into, is how corba and ws distinguish each other when usedf to do legacy integration.

To integrate legacy systems into a bigger platform that interoperates each other, you use CORBA as an "extention" scheme, i.e., corba or web services connects legacy systems to each other as long as they all conform to the standard.

But in terms of technical chanllenge or cost effectiveness, using WS or CORBA to integrate legacies is any different?

Depending on how the legacy works, you still have to use screeen scraping or object mapping or similar thicks to make the legacy work with a CROBA vendor product, or WS vendor product.
 
I agree. Here's the link: http://aspose.com/file-tools
