Answer 1

Check with that below dependency is it present or not ??

<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0-m01</version>
</dependency>

Answer 2

You seem to be missing the dependency on javax.ws.rs. Make sure that you have this in your pom.xml and try again.

Whatever tutorial you're following should have quite a bit of information about these dependencies as well.
