According to its homepage RESTEasy is

... a fully certified and portable implementation of the JAX-RS specification.

So JAX-RS is a specification of how a library for implementing REST APIs in Java should look like and RESTEasy is one implementation of that specification.

This effectively means that any documentation on JAX-RS should apply 1:1 to RESTEasy as well.
