I use MOXy to create XML responses for a SOAP web service and I need some tags to be printed even though the value is null. I'm using MOXy's XmlNullPolicy annotation for that purpose.

Here's an example:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "prop1",
    "prop2"
})
@XmlRootElement(name = "Response")
public class Response {
    @XmlElement(name = "Prop1")
    @XmlSchemaType(name = "string")
    @XmlNullPolicy(nullRepresentationForXml = XmlMarshalNullRepresentation.EMPTY_NODE)
    protected MyEnumType prop1;
    
    @XmlElement(name = "Prop2")
    @XmlNullPolicy(nullRepresentationForXml = XmlMarshalNullRepresentation.EMPTY_NODE)
    protected String prop2;
    
}

I'm expecing the following resulting XML:

<Response>
    <Prop1/>
    <Prop2/>
</Response>

But I'm getting:

<Response>
    <Prop2/>
</Response>

Prop1 is missing even though XmlNullPolicy annotation is correctly defined.

Any idea or solution?
