There is no SOAP service at this location

Following Error will be shown when I do not add ?wsdl to address

My Customer class

package myclasses;

public class customer {
private String name;
private int age;
private int[] rankings;

public customer(){
    //Any initializations here.
}

public customer(String n, int a) {
    this.name = n;
    this.age = a;
    rankings = new int[2];
    rankings[0] = 1;
    rankings[1] = 2;

}

public String getName() {
    return name;
}

............Rest of setter and getters goes here .............

}

My Web service class

     package services;

import myclasses.customer;

import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.WebResult;
import javax.jws.soap.SOAPBinding; 

@WebService (name="Hellos", 
targetNamespace="http://localhost:8081/Mywebservice2/services/Hellos")  
@SOAPBinding  
(  
      style = SOAPBinding.Style.RPC,  
      use = SOAPBinding.Use.LITERAL,  
      parameterStyle = SOAPBinding.ParameterStyle.WRAPPED  
 )  
public class Hellos {

    @WebMethod
    public @WebResult(name="name",partName="name") String getName(){
        return "Jack";
    }
    
    @WebMethod
    public @WebResult (name="customers",partName="customers") customer[] mycustomers() {
        customer[] cus = new customer[2];
        cus[0] = new customer("Jack", 28);
        cus[1] = new customer("Alex", 29);
        return cus;
        
    }
}

Answer 1

The value type "myclasses.customer" used via the service class "services.Hellos" does not have a public default constructor

Just use this in customer class.

public customer()
{
  //Any initializations here.
}
