Simple Unmarshalling example problem

Question

First of all let me say that I'm very new to this technology so please excuse my ignorance.
Now that being said. I'm trying to do a very simple JAXB unmarshaller example.
I have the following xml format:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Books>
     <authFName>F. Scott</authFName>
     <authLName>Fitzgerald</authLName>
     <bookISBN>0-471-398233</bookISBN>
     <bookName>The Great Gatsby</bookName>
     <printDate>
          <month>07</month>
          <day>30</day>
          <year>1978</year>
     </printDate>
     <publisher>Scribners</publisher>
</Books>Now I've got a books class
package com.example.book;
@javax.xml.bind.annotation.XmlRootElement(name="Books")
public class Books
     private String bookName;
     private String bookISBN;
     private Date printDate;
     private String publisher;
     private String authFName;
     private String authLName;
     public Books() {}
     public Books(String bookISBN, String bookName, int mth, int day, int year, String publisher, String aFName, String aLName)
          this.setBookISBN(bookISBN);
          this.setBookName(bookName);
          printDate = new Date(mth,day,year);
          this.setPublisher(publisher);
          this.setAuthFName(aFName);
          this.setAuthLName(aLName);
     public String getAuthFName()
          return authFName;
     public void setAuthFName(String authFName)
          this.authFName = authFName;
     public String getAuthLName()
          return authLName;
     public void setAuthLName(String authLName)
          this.authLName = authLName;
     public void setBookName(String bookName)
          this.bookName = bookName;
     public String getBookName()
          return bookName;
     public void setBookISBN(String bookISBN)
          this.bookISBN = bookISBN;
     public String getBookISBN()
          return bookISBN;
     public void setPublisher(String publisher)
          this.publisher = publisher;
        public Date getPrintDate() {
          return printDate;
     public String getPublisher()
          return publisher;
}and a Date class:
package com.example.book;
public class Date{
     private int month;
     private int day;
     private int year;
     public Date(){}
     public Date(int m, int d, int y){
          setDate(m,d,y);
     private void setDate(int m, int d, int y){
          setMonth(m);
          setDay(d);
          setYear(y);
     private void setYear(int y) {
          this.year = y;
     private void setDay(int d) {
          this.day = d;
     private void setMonth(int m) {
          this.month = m;
}And here's my test class:
package com.example.xml;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import com.example.book.Books;
public class UnmarshallingExample
     public static void main(String[] args) throws JAXBException, FileNotFoundException
          JAXBContext jc = null;
          Unmarshaller u = null;
          Books b1 = new Books();
          jc = JAXBContext.newInstance(b1.getClass());
          u = jc.createUnmarshaller();
          b1 = (Books)u.unmarshal(new FileInputStream("UnMarshallingOutput.xml"));
          System.out.println("FirstName: " + b1.getAuthFName());
          System.out.println("LastName: " + b1.getAuthLName());
          System.out.println("ISBN: " + b1.getBookISBN());
          System.out.println("Book Name: " + b1.getBookName());
          System.out.println("Print Date: " + b1.getPrintDate());
          System.out.println("Publisher: " + b1.getPublisher());
}The result of this code is that my print date is null. I'm sure it has something to do with a missing annotation or something in the date class. But I haven't had any luck, does anybody have any suggestions?
Sorry for the length...
Cheers...

Random attempt: I see no setPrintDate() on Books...
