[JBoss] Error using Restful with JBOSS runtime, bad arguments passed to RestService

I have created a maven webapp and I'm trying to use the restful services and a JBoss 7.0 runtime.

I've changed the web.xml to call the restful services using javax.ws.rs from which I have also added the jar to the build path. The server starts perfectly, so there is no errors or failures in related to the web.xml file and I can successfully call the first page.

I've wrote a class called RestService which is supposed to do something when I call another URL (to be precise localhost:8080/myPrj/rest/hello/first), but when I call the URL it shows an error on my eclipse console and on the web browser.

What am I doing wrong?

Please help a newbie

this is my web.xml

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">

<servlet-mapping>
<servlet-name>javax.ws.rs.core.Application</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>


This is the class Restsservice

import javax.ws.rs.*;
import javax.ws.rs.core.*;
import url_checker.*;


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


@GET
@Path("first")
@Produces(MediaType.TEXT_PLAIN)
public String hello(){
System.out.println("here");
return "Hi everyone";
}
@GET
@Path("go")
public String go(){
runProgramMethod();
return "<p1>Programm running</p1>";
}
private void runProgramMethod() {
MainPauserMethod runner = new MainPauserMethod();


}
}


This is the error message on the browser:

type Status report

And this one on the console on eclipse:
