Sergey Beryozkin commented on CXF-4782:
---------------------------------------

I think you can simply write a basic CXF interceptor which will sit at any stage before or at the one used by JAXRSInInterceptor and replace "_type" with "format" by updating Message.QUERY_STRING on the message; and also update RequestPreprocessor by getting it from the message:

{code:java}
ProviderFactory providerFactory = ProviderFactory.getInstance(message);
RequestPreprocessor rp = providerFactory.getRequestPreprocessor();
{code}

Hope it will do it

> I need to add the ability to override the Accept header using a query parameter.  I know CXF supports "_type", but there are two problems with the way that is implemented that won't work for us.  1) We need to parameter name to be "format" instead of "_type" and currently this is not configurable.  2) We need to be able to pass in a map of special type that we would like to map.  This would added to the SHORTCUTS.  
> Since the current RequestPreProcessor doesn't allow for either one of those, I decided to write a JAXRS Filter/RequestHandler.  The problem I found is that the JAXRSInInterceptor has already looked up the acceptContentType before my RequestHandler.handleRequest() method is called.  Thus, I am unable to override it using this approach.  
> Ideally, the fix would be to simply make them configurable in the RequestPreProcessor.  However, I am not quite sure how that would be done since this is not a class that is managed/configured in the IoC/DI container.  
> Another approach would be to call the RequestHandlers before resolving the acceptContentType.
