What Maven Artifact Contains javax.ws.rs.Path?

What Maven Artifact Contains javax.ws.rs.Path?

I am working through examples in Restful Java with JAX-RS by Bill Burke.
I'm using intellij and created a Maven project to make a "Hello World" web
service. I understand that JAX-RS is a specification, and not an
implementation. I would like to try the Apache CXF implementation.
How do I find out what jar, or what Maven artifact contains the necessary
classes to:
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.GET;
