javax.ws.rs package

I am learning RESTful Web Services and all the tutorials use javax.ws.rs.* package. But with JDK 6 and JDK 7, my Eclipse doesn't seem to recognize javax.ws package. What am I missing here?

Do you have jsr311-api.jar in your classpath? – Co 4/4, 2012 at 3:25

Adding jsr311-api.jar fixed the issue. But the java 6 API mentions these classes. Not sure why I need to add it separately. – Harness 4/4, 2012 at 6:3

javax.ws.rs is not a JDK package; it is a server-side API that forms part of the Java EE specification. You would need to include a Java EE runtime on your classpath or source an implementation from a 3rd party if you're going the self-assembly route (e.g. using Tomcat.)

Why is jax-ws (Soap based) shipped with JDK but not jax-rs (Rest based)? – Whitley 18/2, 2014 at 16:14

@Whitley I guess it is because it is much easier to write a REST client than a SOAP client but I can't give a definitive answer. – Periwig 18/2, 2014 at 16:34

Interesting, jax-rs does come with Metro stack and Metro is shipped with JDK6. This means not full stack of Metro is shipped with JDK. Confused! – Whitley 18/2, 2014 at 16:43

@Whitley I do not think Metro is a JAX-RS implementation. I believe Jersey is the JAX-RS reference implementation. – Periwig 18/2, 2014 at 16:53

You're may be missing Jersey installation, or something in your environment configuration. Try also installing Eclipse WPT. You can follow this tutorial, it covers prerequisites and basic installation procedures as well.

I added jersey installation to classpath. But Jersey does not have javax.ws.rs package. shouldn't javax.ws.rs package be in Java 6 SDK? But it doesn't seem to be. – Harness 4/4, 2012 at 6:0
