Problemi con Rest, non riesco a trovare la servlet

Salve.
Ho approdato alla tecnologia Rest.
Riesco a far avviare la pagina di index.jsp del progetto ma ho un errore di all'indirizzo
http://localhost:8080/SimpleRestWeb/rest/hello/Max:
HTTP Status 404 -

type Status report
message
description The requested resource is not available.

Apache Tomcat/7.0.55

Questo è il file xml:

    <servlet>
        <servlet-name>helloworld</servlet-name>
        <servlet-class>
                     com.sun.jersey.spi.container.servlet.ServletContainer
                </servlet-class>
        <init-param>
             <param-name>com.sun.jersey.config.property.packages</param-name>
             <param-value>com.rest.example</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>helloworld</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>
</web-app>

sotto c'è il file della servlet:

package com.rest.example;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;


@Path("/hello")
public class HelloWorld {

    @GET
    @Path("/{param}")
    public javax.ws.rs.core.Response getMsg(@PathParam("param") String msg) {
    String output = "Ben venuto nel mondo Rest: " + msg;
    return Response.status(200).entity(output).build();
    
    }
}

Qualcuno ha qualche idea? Grazie
