Could not read mappings from resource
请问我编写好Product.hbm.xml并在hibernate.cfg.xml中添加，代码如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC  
  "-//Hibernate/Hibernate Mapping DTD 3.0//EN"  
  "http://hibernate.sourceforge.net/hibernat-mapping-3.0.dtd">  
<hibernate-mapping>
<class name="petstore.dao.Product" table="products">
<id name="id" column="productId">
<generator class="native"/>
</id>
<property name="pName" column="name"/>
<property name="description" column="description"/>
</class>
</hibernate-mapping>
做junit测试时候 报错

Junit代码如下：
public class C02Test extends TestCase{
  public void testAddProduct()throws Exception{
  Session session=HibernateSessionFactory.getSession();
  Transaction tx=null;
  try{
  tx=session.beginTransaction();
  Product p=new Product();
  p.setName("hibernate");
  p.setDescription("ORM Framework");
