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...

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
