I need good tool to prepare web-service on the base of ready WSDL and
schema files. Service is called SIRI.
I have tried gSOAP and Axis2/C projects. None of them fulfill my
requirements. gSOAP does not correctly convert complex types into C
structures (especially subsequences) and Axis2/C throws exceptions
without any further explanation.

If there are no better tools (read: more experienced) then maybe
something to another language?

I try to use JAXB, but it is final solution if other fail.
