hibernate3 + mysql5.0的问题

兄弟这两天刚刚开始学习hibernate，从网上下载了最新的hibernate3，数据库使用mysql5.0；我对hibernate和mysql都不是很熟。  
  出现了问题：  
  信息:   schema   export   complete  
  Exception   in   thread   "main"   org.hibernate.HibernateException:   No   CurrentSessionContext   configured!  
  at   org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:506)  
  at   events.EventManager.CreateAndStoreEvent(EventManager.java:45)  
  at   events.EventManager.main(EventManager.java:37)  
  程序执行时的输出和xml文档的配置内容已经贴了出来，请各位大侠过目瞅瞅是什么原因？  
  程序执行输出：

如果你是用hibernate.cfg.xml的话  
  生成session的方法应该是用以下这种文件  
  public   static   SessionFactory   sessionFactory;  
  private   static   Configuration   configuration;  
  static   {  
   
  try   {  
  configuration   =   new   Configuration();  
   
  sessionFactory   =   configuration.configure().buildSessionFactory();  
  }   catch   (Throwable   ex)   {  
   
  throw   new   ExceptionInInitializerError(ex);  
  }  
  }Top

sessionFactory   =   new   Configuration().configure().buildSessionFactory();  
  Session   session   =   sessionFactory.getCurrentSession();  
  我就是用的这种方法啊！  
  不知道是不是我配置什么地方不对啊！Top

getCurrentSession   不对  
  用openSession    
   
  你再看下   hibernate   api   doc   对   openSession   和   getCurrentSession   的说明Top

谢谢各位仁兄，我改成了openSession就成功了，但是不知道为什么我昨天晚上也改成openSession就没有成功！呵呵！  
  能解释一下openSession和getCurrentSession()的不同吗？  
  我是根据Hibernate   Reference   Documentation里面的例子写的程序。Top
