Do I necessarily need a third party framework for a Java-based REST service (JSON)?

Question

Of course JAX-RS should work without any additional framework like JAX-WS also does. But in JAX-WS, I just put some annotations on a POJO, create a self hosted service with one single line of code and that's it.

I can't find any tutorials or resources that show how to do the same with JAX-RS. Nearly every tutorial uses Jersey (or Easyrest etc.) and at least Maven. Isn't there an easy way to set up a Rest based service like it can be done with JAX-WS?

Thank you

edit: Hm, I think annotations like @Path etc. aren't available without these frameworks? My eclipse cannot reference/find them :(

JAX-RS is an API. Jersey and RESTEasy are its implementations. Jersey, is the 'reference' implementation of JAX-RS, and therefore shows up frequently in tutorials (after all, one needs some implementation of the API to use it).
