Java Unmarshalling issue (jaxb)

Question

Below mentioned are the xml file i want to unmarshal and create java object:

test.xml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.test.co.uk/mc/host/201602/">
   <soapenv:Header/>
   <soapenv:Body>
      <getCustomerDetailsResponse>
      <name>test</name>
      <age>20</age>
      <company>test</company>
      </getCustomerDetailsResponse>
   </soapenv:Body>
</soapenv:Envelope>

To read xml file, i am using below code:

Customer.java

package jaxbTest;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "soapenv:Envelope", namespace = "http://schemas.xmlsoap.org/soap/envelope/")
public class Customer
{
  @XmlElement(name = "name", namespace = "getCustomerDetailsResponse")
  public String name;
  @XmlElement(name = "age", namespace = "getCustomerDetailsResponse")
  public int age;
}

Below mentioned is the main file

JaxbTest.java

package jaxbTest;


import java.io.File;  
import javax.xml.bind.annotation.*;
import java.util.List;  

import javax.xml.bind.JAXBContext;  
import javax.xml.bind.JAXBException;  
import javax.xml.bind.Unmarshaller; 

public class JaxbTest {

      public static void main(String[] args) throws Exception {

           JAXBContext jc = JAXBContext.newInstance(new Class[] {jaxbTest.Customer.class});
            Unmarshaller unm = jc.createUnmarshaller();

            // Unmarshal Customer
            File customerXML = new File("src/jaxbTest/test.xml");
            Customer customer = (Customer) unm.unmarshal(customerXML);
            System.out.println(customer.age);
        }

}
