休眠.cfg.xml未找到

我是Hibernate的新手，正在阅读这本书“Java Persistence with Hibernate”，我正试图从那里实现这个例子。到目前为止，我的Ant构建是成功的，但是当我尝试执行包含main方法的类时，我收到以下错误消息：

19-Nov-2011 18:40:09 org.hibernate.cfg.Environment <clinit>

很明显，休眠找不到我的配置文件，它位于根目录下。

项目

+lib
<all required libraries>
+src
  +hello
    HelloWorld.java
    Message.java
    message.hbm.xml
  +persistence
    HibernateUtil.java
build.xml
hibernate.cfg.xml

我的完整源代码可以在这里找到：http://pastebin.com/bGDUrxUf

我有一个正在运行的MySQL服务器，带有数据库休眠应用程序和表消息

谢谢:)
