Re: [Resteasy-users] Adding jackson-module-afterburner

Hi Anthony,

I see that com.fasterxml.jackson.jaxrs.base.ProviderBase, from which 
org.jboss.resteasy.plugins.providers.jackson.ResteasyJackson2Provider is 
indirectly derived, has a method

     /**
      * Method called to locate {@link ObjectMapper} to use for 
serialization
      * and deserialization. If an instance has been explicitly defined by
      * {@link #setMapper} (or non-null instance passed in constructor), 
that
      * will be used.
      * If not, will try to locate it using standard JAX-RS
      * <code>ContextResolver</code> mechanism, if it has been properly 
configured
      * to access it (by JAX-RS runtime).
      * Finally, if no mapper is found, will return a default unconfigured
      * {@link ObjectMapper} instance (one constructed with default 
constructor
      * and not modified in any way)
      *
      * @param type Class of object being serialized or deserialized;
      *   not checked at this point, since it is assumed that unprocessable
      *   classes have been already weeded out,
      *   but will be passed to <code>ContextResolver</code> as is.
      * @param mediaType Declared media type for the instance to process:
      *   not used by this method,
      *   but will be passed to <code>ContextResolver</code> as is.
      */
     public MAPPER locateMapper(Class<?> type, MediaType mediaType);

So, for example, you could try

          ResteasyJackson2Provider provider = new 
ResteasyJackson2Provider();
          ObjectMapper mapper = provider.locateMapper(Object.class, 
MediaType.APPLICATION_JSON_TYPE);

in a resource method. Does that work for you?
