对于您所有的信息，我正在开发一个使用Eclipse与Eclipse进行交互的java项目，因此我使用ojdbc14.jar和hibernate3.jar以及所有7个jar文件更新了BUILD PATH Hibernate所需的文件夹。与Hibernate进行交互时出错
我在这里粘贴了所有课程。 在运行主Manager.java，我得到一个错误“异常线程‘main’org.hibernate.InvalidMappingException：无法从资源解析映射文件COM /拉拉/ Person.hbm.xml”。可有人告诉哪里我犯了一个错误。
错误日志

@skaffman我只是忘了，因为我在如痴如醉的状态 – 2012-01-31 23:13:08
仍不足以提的错误。除此之外，还有更多的错误。 – skaffman 2012-01-31 23:14:29
@skaffman现在我粘贴了整个错误日志，以前我遇到过这个问题 – 2012-01-31 23:18:14
