Using the xjc:superClass customization in jaxb

Question

Hi,
I'm having some problems with the <xjc:superClass> customization when I use this, the properties of my superClass don't get serialized to xml the xml file is empty. Can sombody help me with this problem?
this is my xsd:
<xsd:schema jaxb:version="1.0" jaxb:extensionBindingPrefixes="xjc" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc">
     <xsd:annotation>
          <xsd:appinfo>
               <jaxb:globalBindings generateIsSetMethod="true">
                    <xjc:serializable/>
                    <xjc:superClass name="VtProduct"/>
               </jaxb:globalBindings>
          </xsd:appinfo>
     </xsd:annotation>
     <xsd:element name="fastrackProduct">
</xsd:schema>and this is my VtProduct from witch the fastrackProduct should extend:
public class VtProduct implements Serializable {
    private String code;
    private String description;
    private int priceInCents;
    private String deliveryName;
    private String uid;
    public VtProduct() {
    public String getCode() {
        return this.code;
    public void setCode(String code) {
        this.code = code;
    public String getDescription() {
        return this.description;
    public void setDescription(String description) {
        this.description = description;
    public int getPriceInCents() {
        return this.priceInCents;
    public void setPriceInCents(int priceInCents) {
        this.priceInCents = priceInCents;
    public String getDeliveryName()  {
        return this.deliveryName;
    public void setDeliveryName(java.lang.String deliveryName)  {
        this.deliveryName = deliveryName;
    public String getUid() {
        return this.uid;
    public void setUid(java.lang.String uid) {
        this.uid = uid;
}This is what i'm trying to do im my main class:
FastrackProductImpl po = new FastrackProductImpl();
po.setCode("1234567890");
po.setDeliveryName("Delivery name");
po.setDescription("Description");
po.setPriceInCents(1000);
po.setUid("0987654321");
po.setFastrackProductId("FSID1234");
FileOutputStream mout = new FileOutputStream("fastrackProduct.xml");
marshaller.marshal(po, mout);
mout.close();

Thanks a lot!
Btw, are all the tags that a .xjs file takes documented anywhere??
Its feels rather silly to struggle so much for little things.(Moreover, I am an XML rookie ...so I don't have much f an instinct when it comes to that!)
Thanks again.
