Yes. JAX-RS (the standard implemented by Jersey), which is part of the often maligned Java EE, is a (surprisingly?) well designed REST "microframework". Java EE in general has come a long way from the monster it used to be, and is becoming quite pleasant.

You can use Servlet + Jersey. It's just one dependency away and minimal web.xml config (or spring-jersey...whichever). It's not necessarily tied to Java EE albeit Java EE app-server _must_ implement JAX-RS properly.

Both Servlet and JAX-RS are pretty central pieces of Java EE. But Java EE is now really a collection of modules that you can pick and choose.
