JAXBElementRef does not generate nillable="true"

Question

for the request for my web service, I wanted to differ between requested null value and missing tag. In other words I needed the following element definition:

<xs:element minOccurs="0" name="minzeronil" nillable="true" type="xs:string"/>

I developed the web service code-first, so I defined the element using JAXBElementRef:

@XmlRegistry
public class ObjectFactory {

  @XmlElementDecl(name = "minzeronil", namespace = XmlNamespace.MY_SERVICE)
  public JAXBElement<String> createMinzeronil(final String value) {
    return new JAXBElement<String>(new QName(XmlNamespace.MY_SERVICE, "minzeronil"), String.class, value);
  }

}

Now, I expected to see nillable = "true" in the definition of the element. Instead, I got:

<xs:element name="minzeronil" type="xs:string"/>
<xs:element ref="tns:minzeronil" minOccurs="0"/>

How can I generate nillable = "true" from my java code? ... and still use JAXBElement in my code and its methods like isNil() ...

UPDATE: I deploy the code on glassfish, so glassfish is the one that generates the wsdl and xsd.

use @XmlElement(nillable = true) in your Java Class

@XmlElement(nillable=true)
public String getAString() {
    return AString;
}

if only it were that straightforward ... when I use this notation, I will not be able to check if the attribute is true in my java code. That's why I used `@XmlElementRef` – user1414745 Nov 22 '13 at 21:09
