I understand. Its a question to Yoko developers.

You say you have CORBA service and WS client implemented with
Dispatch<Source> should work? Or what you mean exactly with working
Dispatch?
Talking about WS client calling CORBA we have tried to use dynamic
proxy over CORBA and it doesnt work:
QName svcQname = new QName(
"http://schemas.apache.org/yoko/idl/calc";,
"com.pikeelectronic.calc.CalculatorCORBAService");
QName portQName = new QName(
"http://schemas.apache.org/yoko/idl/calc";,
"com.pikeelectronic.calc.CalculatorCORBAPort");
File wsdl = new File("calc-soapbinding.wsdl");
Service svc = Service.create(wsdl.toURL(),svcQname);
ComPikeelectronicCalcCalculator calc =
svc.getPort(portQName, ComPikeelectronicCalcCalculator.class);
double result = calc.add(4, 5);
System.out.println(result);
When I run this with SOAP binding it works but when I try to do this
with CORBA binding I am getting exception:
INFO: Interceptor has thrown exception, unwinding now
