I've been doing some work with the JAX-RS reference implementation (Jersey). I know of at least two other frameworks (Restlet & Apache CXF).
My question is: Has anyone done some comparison between those frameworks and if so, which framework would you recommend and why?
FWIW we're using Jersey as its packed full of features (e.g. WADL, implicit views, XML/JSON/Atom support) has a large and vibrant developer community behind it and has great spring integration.
If you use JBoss/SEAM you might find RESTeasy integrates a little better - but if you use Spring for Dependency Injection then Jersey seems the easiest, most popular, active and functional implementation.
