十分钟在jb里面运行hibernate的简单例子。

n+1次了，后面1000条要象前面3条一样加上事务。

谢谢，问题确实在这儿。

不好意思，来麻烦各位了，但这个错误我实在搞不定啊：org.dom4j.DocumentException: Invalid byte 1 of 1-byte UTF-8 sequence
在网上搜了一下，有人说也许是因为xml文件头没加：<?xml version="1.0" encoding="UTF-8"?>，但我加了也无济于事。不解……

讨论过n遍了，搜索一下

1、插入数据时每条记录的NEXT_MESSAGE_ID 值是如何保存的，2、Message.hbm.xml中的many to one 能不能讲解一下他的运作思想

我是JB7。mysql数据库运行完后报错。请各位老大多多帮助。谢了。

我的错误更加奇怪了.
    Message message;
    long start = System.currentTimeMillis();
    try {
      for (int i = 0; i < 1000; i++) {
        message = new Message("hello" + i);
        session.save(message);
        session.flush();
      }
      tx.commit();
    } catch (HibernateException ex) {
      tx.rollback();
      System.out.println(ex.toString());
    }
    long end = System.currentTimeMillis();
    System.out.println("添加1000条记录时间－－－" + (end-start)/1000 + "s");
错误讯息:net.sf.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: 0, of class: hello.Message
环境jbuilerX+mysql4.0.19+mysql jdbc 3.0.9+Hibernat 2.1

我这里也出现了问题，不过可能是我的jbuilder用的不好，希望哪位高人能指点一下。
按照楼主的方法，我做好了一个project，编译没有问题，运行时选用run-->hello,结果弹出一个对话框：
Stopped in class with tracing disabled

Hit breakpoint in class java.net.URLClassLoader$1.Tracing is disabled for this class.



        

想知道我到底在什么地方有问题？

现在又有新的报错信息
log4j:WARN No appenders could be found for logger (net.sf.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
Hit uncaught exception net.sf.hibernate.MappingException

已经搞好了，我没有把log4j.properties copy过来，不过没有看到哪篇文章里提到过这个，请问这是什么原因？

环境：win2000+jbuilder9+mysql4.0.17+hibernate2.1
