mocking problem: non-WSDL services

Hey,

I would like to ask if there is any way to create mock services from non-WSDL (and non-WADL) files. (I have to work on a project, where services are not based on w3c compliant SOAP and WSDL, but on a different XML scheme ( http://www.trask.cz/en/integration-framework )).

I know that even the name of soapUI says SOAP, but still wondering

Or does anyone know some kind of transformation (XSLT?) solution to create WSDL first and then create the mocks and manually modify responses to give back not soap but the special format of the framework?

Or maybe is this a good situation to extend soapUI through the API (Actions/Listeners) to be able to handle these kind of formats?

Other ideas for workaround? Any input is welcome

Thanks,
András Liter
