Hello, the operation info and CORBA parameters are not the reason why do we need the support. We would like to create a web service provider that will be accessible from CORBA client. We have no clue how to do this because we cannot simply create Provider<CorbaMessage>, Provider<SOAPMessage> or even Provider<Source>. Exception occurs when we try this so it seems nobody ever used it before and the code contains a bug or we are doing something wrong.
On the other side we are also trying to call (normal) CORBA service with web service client implemented in CXF/Yoko dynamicaly (DII client). We do not know if is it possible to create SOAPMessage and pass it to Yoko CORBA binding along with WSDL file to make a dynamic call. It seems to me the terms "corba cxf binding" and "dynamic" cannot live together... Best regards, Lukas 2007/8/2, Liu, Jervis <[EMAIL PROTECTED]>: > Hi, have a new question.
