Hola estoy empesando con hibernate y pues al ralizar mi primera aplicacion tengo algunos problemas, espero que alguien me pueda ayudar.
la clase que tengo es:
package example.productos;
public class Book {
private int id;
private String title;
private String author;
private String isbn;
private int pages;
private int copyright;
private float cost;
public Book() {
}
public void setId(int i) {
id = i;
}
public int getId() {
return id;
}
public void setTitle(String s) {
title = s;
}
public String getTitle() {
return title;
}
public void setAuthor(String s) {
author = s;
}
public String getAuthor() {
return author;
}
public void setIsbn(String s) {
isbn = s;
}
public String getIsbn() {
return isbn;
}
public void setPages(int i) {
pages = i;
}
public int getPages() {
return pages;
}
public void setCopyright(int i) {
copyright = i;
}
public int getCopyright() {
return copyright;
}
public void setCost(float f) {
cost = f;
}
public float getCost() {
return cost;
}
}
mis archivos de mapeo son
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<property name="copyright"/>
<property name="cost">

</property>
</class>
</hibernate-mapping>
y esta es la plicacion
package example.productos.book;
import java.io.*;
import org.hibernate.*;
import org.hibernate.cfg.*;
import example.productos.Book;
public class BookTest {
static SessionFactory sessionFactory;
public static void main(String [] args) {
try {
Configuration cfg = new Configuration().addClass(Book.class);
sessionFactory = cfg.buildSessionFactory();
Session session = sessionFactory.openSession();
//Session session = Config().SessionFactory().
//HibernateSession.currentSession();
Book book = new Book();
book.setTitle("Professional Hibernate");
book.setIsbn("003948490309");
book.setAuthor("Some Guys");
book.setPages(300);
book.setCost(29.99f);
session.save(book);
session.flush();
session.close();
} catch (Exception e) {
e.printStackTrace();
}
}
cuando ejecuto la aplicacion me mand un error el cual es el siguiente
