Hi, This is how i see it working...
Soap client invokes on the synapse/router endpoint. At this stage, the synapse/router acts like a server side & would receive the soap message on the inbound & it would have marshalled them as proper parameters... Then on the outbound it would become a webservice client for the corba web service & invoke it with the marshalled parameters. The xsd type to corba type mapping are done using the idltowsdl tool. There is a type mapping section in the generated wsdl which specifies the default mapping. I dont know much about how synapse mediator works but i think this should easy enough to implement. I am trying to write a simple bank demo which would use a soap client & invoke on a corba server via a router. I will let you know once i have that demo working... - Balaji On 7/31/06, Christian Galbavy <[EMAIL PROTECTED]> wrote:
Hi, ok I am just writing my thoughts and would like to get some comments, if I am right. So lets say I have a CORBA object with the approbriate idl. I can get the approbriate WSDL from the Yoko tool idl2wsdl. And then Yoko can invoke the Corba call with that. So what would I have the programm for that and where does the actual type mapping from the SOAP-types (xsd-types) to the Corba-types (typecodes)? For the beginning I only want to see the performing of this calls, so the dynamic part with the Interface Repository calls would follow later. For this time I asume that I have got the WSDL file from the idl file from somewhere and the approbriate Corba method is available. Then I get my SOAP call, and build my Corba call manually. Another question for me is, which role does Synapse play here. What can Synapse do with this wsdl file? I still try to understand the mediator technology, so please do not wonder about silly questions :-) Regards Christian -------- Original-Nachricht -------- Datum: Fri, 28 Jul 2006 16:24:41 +0100 Von: "Nolan, Edell" <[EMAIL PROTECTED]> An: yoko-dev@incubator.apache.org, [EMAIL PROTECTED] Betreff: RE: Soap-corba bridge > Hi, > > Balaji is right this is a perfect case to use Yoko.
