Re: [Resteasy-developers] Marshalling Object reference as Link

[Solomon D. <sd...@gm...>]

IMHO, you're on the right track with this thought.  To do this, you have to
create a custom MessageBodyWriter + renderer.  I've been working on
something like this for a while now: https://github.com/skyscreamer/yoga.
There's a lot of great use cases for this type of technology, as well as a
handful of other implementations.
