Sure. Say you offer two media types like in your example below, in
your method you write something along the following lines:
@Path(...)
public ResourceClass {
@Context Request request;
@GET @Produces( { MediaType.APPLICATION_JSON,
MediaType.APPLICATION_XML })
public someMethod() {
List<Variant> availableVariants =
Variant.mediaTypes(MediaType.APPLICATION_JSON_TYPE,
MediaType.APPLICATION_XML_TYPE).add().build();
Variant bestMatch = request.selectVariant(availableVariants);
MediaType bestMatchingType = bestMatch.getMediaType();
return getSomeEntity(bestMatchingType);
}
}
The call to selectVariant will have Jersey check the HTTP Accept
header for you and work out which of the media types you offer best
matches what the client requested.
