Yes, I can generate my method as expected using the tMap argument. But, I don't understand what I'm doing (i.e. the purpose of tMap) and why I need to do that. The expected behavior would be to add a method parameter (else how to access the information the client sent?), why do I need to add extra configuration to make this work?
Concerning the returned responses: In the case the HTTP response's body is empty, the operation method returns nothing (void). Even if I build an instance of Response, how to return it? Concerning the use of filters, I don't understand how it can help since the decision about which response to send (i.e. status code, various HTTP headers...) is taken inside the body of the processing method. I don't have this decision information inside the filter. In the case my HTTP response's body should include a XML representation, the generated method returns an instance of the class corresponding to the XML type (e.g. AType according to my previous example). So, there is no Response instance returned (at least inside the method), and I get the same issue. The solution seems to be accessing some sort of context inside the method, and customize the returned response through this context, but I don't know if there is such a construct?

In meantime, add ResponseHandler filter (on CXF 2.6.x) or ContainerResponseFilter (on CXF 2.7.0) and add a required header from there... > Also, what if for a given request, different responses may be returned > according to how the operation performed?

At the moment the simplest thing to do is to <response status="200 400 401"> etc Creating multiple responses is also valid but as far as the code generation is concerned, it won't make any difference, given that at the code level the relevant exceptions are all runtime ones. However, it can be better for the reader of WADL because you can attach specific descriptions to different response elements...
