Hi
I've got a problem when I'm trying to use the lazy property fetching.
Here is what I'm doing:
I've enhanced the Product class which I want to use and then, I try to test it. The problem is that the Configuration can't create any SessionFactory.
If I delete the lazy attribute in the mapping file or if I don't enhance the class, no exceptions are raised.
Thus I'm asking some help...

Hibernate version: 3.0 alpha


The exception happen when I'm creating the sessionFactory:
Configuration cfg = new Configuration()
.addClass(Product.class);
SessionFactory sf = cfg.buildSessionFactory();





Mapping documents:
Product
class:
package fr.digimind.jdo.hibernate;

public class Product {
private String id;
private String name;
private double price;
private int amount;

public int getAmount() {return amount;}
public String getId() {return id;}
public String getName() {return name;}
public double getPrice() {return price;}
public void setAmount(int i) {amount = i;}
public void setId(String string) {id = string;}
public void setName(String string) {name = string;}
public void setPrice(double d) {price = d;}
}

mapping file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping
PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="fr.digimind.jdo.hibernate">
