file not found Exception web service

Question

i have a web and mobile application that are powered by web service the problem that every time I am trying to recover a user I get the following message "java.io.filenotfoundexception" (followed by my URL) and the 404 response code. I’ve looked everywhere and found nothing that could help me. I’m doing the project by MAVEN and I don’t know if some dependency is missing or not ( at least there’s no error regarding this, but I’ll leave pom.xml for you to look at). Can someone please help me?

ps: the process arrives at "int code = Connection.getResponseCode();" and does not go to the web service as it should

this code refers to my main one that I am using as a test

String nome ;
    String email;
    String senha;
    long codigo = 2;
        URL url;
    try {
        url = new URL("http://localhost:8084/WebServiceMavenDivulgueAqui/webresources/webService/usuario/recuperarPorId?id="+codigo);

        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setRequestMethod("GET");

        int code = connection.getResponseCode();
        System.out.println(code);

        InputStream inputStrem = connection.getInputStream();
        BufferedReader br =  new BufferedReader(new InputStreamReader(inputStrem));

        String a;
        StringBuilder stringBuilder = new StringBuilder();
        while ((a  = br.readLine()) != null){
         //a += br.readLine();
         stringBuilder.append(a);
        }
      //  System.out.println(stringBuilder.toString());
        connection.disconnect();

         JSONObject jsonObject;

         JSONParser parser = new JSONParser();  

        jsonObject = (JSONObject) parser.parse(stringBuilder.toString());

        codigo = (long) jsonObject.get("codigo");
        nome = (String) jsonObject.get("nome");
        email = (String) jsonObject.get("email");
        senha = (String) jsonObject.get("senha");

        System.out.println("o codigo é :" + codigo + " nome : " + nome 
        + " email : " + email + " senha : " + senha);

    } catch (MalformedURLException ex) {
        JOptionPane.showMessageDialog(null, "erro de URLException conexao ao rest ( recuperar usuario)\n" + ex);
    } catch (IOException ex) {
        JOptionPane.showMessageDialog(null, "erro de IOException conexao ao rest ( Recuperar usuario) \n" + ex);
    } catch (ParseException ex) {
        JOptionPane.showMessageDialog(null, "erro de ParseException conexao ao rest ( Recuperar usuario) \n" + ex);
    }

that code refers to the web service method

 @GET
@Produces(MediaType.APPLICATION_JSON)
@Path("usuario/recuperarPorId")
public String recuperarUsuarioPorId(@QueryParam("id") Long json){

    UsuarioDao u = new UsuarioDao();
    BeansUsuario mod = new BeansUsuario();

    mod.setPesquisarPorId(json);
    mod = u.buscarPorId(mod);

    Gson g = new Gson();
    return g.toJson(mod);
}

and those are my dependencies on pom.xml

Answer 1

I think it solved when I added these codes in pom.xml

    </dependency>
      <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.8</version>
    </dependency>

    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>1.8</version>
    </dependency>
