How to customize the field name of the generated Java object using JAXB custom bindings?

Question

I'm trying to generate JAXB generated objects for the below sample xsd.

<xs:complexType name="AddressType">   
      <xs:sequence>   
        <xs:element name="USA" type="xs:string"/>   
      </xs:sequence>   
   </xs:complexType>  

and the class that gets generated without any custom bindings is

@XmlAccessorType(XmlAccessType.FIELD)   
@XmlType(name = "AddressType", propOrder = {   
    "usa"  
})   
public class AddressType {   

    @XmlElement(name = "USA", required = true)   
    protected String usa;   

    /**  
     * Gets the value of the usa property.  
     *   
     * @return  
     *     possible object is  
     *     {@link String }  
     *       
     */  
    public String getUSA() {   
        return usa;   
    }   

    /**  
     * Sets the value of the usa property.  
     *   
     * @param value  
     *     allowed object is  
     *     {@link String }  
     *       
     */  
    public void setUSA(String value) {   
        this.usa = value;   
    }   
}  

as you see the field name is "usa" and setters/getters are getUSA/setUSA.

Is there any custom setting/binding to have the field name also be generated as "USA" instead of "usa", that way the field and property are all "USA".

I referred How to customize property name in JAXB?

but that is to customize the property, instead of field.. any help

By the way, I'm using maven-jaxb2-plugin

Example xjb file as in your case : binding.xjb

example :

<jaxb:bindings 
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
version="2.1">

<jaxb:bindings schemaLocation="schema.xsd">
    <jaxb:bindings node="//xs:element[@name='USA']">
        <jaxb:property name="usa" />
    </jaxb:bindings>
</jaxb:bindings>

</jaxb:bindings>

Add -b binding.xjb with your xjc command or configure the binding file location in your maven xjc plugin.
