Andriy Redko keeps pushing CXF to the next level with adding new features nearly every few weeks :-).
One of his latest projects has been to do with wiring Apache HTrace into CXF such that CXF users can HTrace calls starting from CXF clients going to CXF servers and then to such HTrace aware containers as HBase and using the collectors like Zipkin.
I'm looking forward to Andriy talking in detail about it on his blog and at the conferences, but in meantime you can check the documentation. Note that it works not only for JAX-RS but for JAX-WS too: if we can have a new feature working with both frontends then you know it will be done. The demo is here.
Give it a try and stay on top of the web services game :-)
