<hibernate开发及整合应用大全>一书中第二章的例子运行错误,还有人遇到这个问题吗？

Question

我用的是最简单的工具 UltraEdit,把hibernate3.2中的几个包解压到文件夹下
 这几个包是hibernate3.jar，antlr-2.7.6.jar，cglib-2.1.3.jar，asm.jar，
 asm-attrs.jar ，commons-collections-2.1.1.jar，commons-logging-1.0.4.jar，
 dom4j-1.6.1.jar，ehcache-1.2.3.jar ，jta.jar，log4j-1.2.11.jar
 完了后，得到文件夹antlr，javax，net,org

我的配置文件如下：hibernate.cfg.xml<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-mapping
