Running REST with Java (JAX-RS) featuring Jersey on IntelliJ / Tomcat

I am trying to do the following tutorial in IntelliJ on OSX:

http://www.vogella.com/tutorials/REST/article.html

When running the code in Eclipse, everything works fine. But running code in IntelliJ delivers 404s for the same URI.

The program should run on Apache Tomcat Server 8.0.20.

I did what was written in the tutorial, but I can’t understand why it will not work in IntelliJ. I searched for a few days and found a solution.

It seems that something with the deployment is wrong, because index.jsp is working fine.

Hope someone can help me.

Program code:

Hello class:

package com.vogella.jersey.first;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

// Plain old Java Object it does not extend as class or implements 
// an interface

// The class registers its methods for the HTTP GET request using the @GET annotation. 
// Using the @Produces annotation, it defines that it can deliver several MIME types,
// text, XML and HTML. 

// The browser requests per default the HTML MIME type.

//Sets the path to base URL + /hello
@Path("/hello")
public class Hello {

    // This method is called if TEXT_PLAIN is request
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String sayPlainTextHello() {
        return "Hello Jersey";
    }

    // This method is called if XML is request
    @GET
    @Produces(MediaType.TEXT_XML)
    public String sayXMLHello() {
        return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
    }

    // This method is called if HTML is request
    @GET
    @Produces(MediaType.TEXT_HTML)
        public String sayHtmlHello() {
            return "<html> " + "<title>" + "Hello Jersey" + "</title>"
                    + "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
        }

}

web.xml
