Subject Re: The bridge with YOKO-CXF (diagram)
Date Mon, 16 Jul 2007 07:26:27 GMT
Two more questions:

I think I do not need Apache Yoko ORB in the diagram SOAP->CORBA
because the WS Client in the relay uses Apache CXF which translates
the call to IIOP. There is no need to use ORB at all, right?

You may wonder why I used two relays in CORBA->SOAP diagram. I thought
I am not able to call Web Service using CORBA client directly. As I am
inspecting the examples I am finding out it is easy to call a web
service over CORBA even without using CXF or Yoko on the CORBA client.
So the two relays are redundant and my the original idea with only one
relay was ok.

If you agree with me I can export diagrams without proxies for use in
the Yoko documentation or wheresoever.
