calculator restful error deploy

Question

the source of "uts.dae.model.rest.Calculadora" class

 package uts.dae.model.rest;

 import javax.ejb.Stateless;
 import javax.ws.rs.GET;
 import javax.ws.rs.Path;
 import javax.ws.rs.QueryParam;

  /**

  @Stateless

  @Path("/calculadora")


  public class Calculadora {


  @GET 
  public String Suma(@QueryParam("num1") double num1,@QueryParam("num2") double num2)    {
  return Double.toString($Suma(num1,num2));
 }
  @Path("calculadora/suma")
    double $Suma(double num1,double num2) {
    double resultado;
    resultado = num1 + num2;
    return resultado; 
 }

@GET 
public String Resta(@QueryParam("num1") double num1,@QueryParam("num2") double num2)    {
return Double.toString($Resta(num1,num2));
 }
 @Path("calculadora/resta")
    double $Resta(@QueryParam("num1") double num1,@QueryParam("num2") double num2) {
    double resultado;
    resultado = num1 - num2;
    return resultado;

 }

 @GET    
 public String Multiplicacion(@QueryParam("num1") double num1,@QueryParam("num2") double num2)    {
 return Double.toString($Multiplicacion(num1,num2));
  } 
 @Path("calculadora/multiplicacion")
   double $Multiplicacion(double num1,double num2) {
    double resultado;
    resultado = num1 * num2;
    return resultado;

}  



 @GET 
 public String Division(@QueryParam("num1") double num1,@QueryParam("num2") double num2)    {
 return Double.toString($Division(num1,num2));
 }
 @Path("calculadora/Division")
  double $Division(double num1,double num2) {
    double resultado;
    resultado = num1 / num2;
    return resultado;

}


@GET 
public String Modulo(@QueryParam("num1") double num1,@QueryParam("num2") double num2)    {
 return Double.toString($Modulo(num1,num2));
 }
@Path("calculadora/Modulo")
double $Modulo(@QueryParam("num1") double num1,@QueryParam("num2") double num2) {
    double resultado;
    resultado = num1 % num2;
    return resultado;

}
}

when I deploy, the following error occurs, if they have different url:

Answer 1

move all @Path annotations from methods having '$' as the prefix to those public methods, something like this:

@GET
@Path("calculadora/Modulo")
public String Modulo(@QueryParam("num1") double num1,@QueryParam("num2") double num2)    {
    return Double.toString($Modulo(num1,num2));
}

double $Modulo(@QueryParam("num1") double num1,@QueryParam("num2") double num2) {
    double resultado;
    resultado = num1 % num2;
    return resultado;
}

also take a look at this SO post.

The problem is that, since all of the public methods are resource methods which are annotated with @GET, they do not have @Path annotation and their list of arguments are the same, if you send a http GET request to "/calculadora" url there is a ambiguouty that which one the methods should be called, so moving @Path annotations to public methods will resolve the problem.
