一个人事管理系统，各种错误，求指导
用swing，hibernate实现的，遇到了几个错误，由于初学，不知道如何更改，求帮忙.第一个问题：Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
at org.hibernate.cfg.Configuration.<clinit>(Configuration.java:197)
at bishe.hibernate.HibernateSessionFactory.<clinit>(HibernateSessionFactory.java:24)
at bishe.hibernate.BaseDao.queryList(BaseDao.java:21)
at bishe.hibernate.Dao.queryManagerOfNatural(Dao.java:140)
at bishe.frame.DengluFrame.<init>(DengluFrame.java:98)
at bishe.frame.DengluFrame.main(DengluFrame.java:43)
是不是hibernate配置文件问题，怎么修改，
第二个问题：树的叶子节点不能单击打开，错误如下：

还是配置文件问题么，JTree的问题是什么，怎么修改
比较着急，可以加我qq帮忙详细说一下。610952820谢谢了 --------------------编程问答-------------------- 添加slf4j-api-1.6.1.jar和slf4j-log4j12-1.6.1.jar这两个包试试，可以去网上下载 --------------------编程问答-------------------- 我用的1.58的包，出现问题

另外，hibernate3的包中有自带slf4j包的吧， --------------------编程问答-------------------- 换jar 要么就是多余的jar
--------------------编程问答-------------------- 看包是否重复？ --------------------编程问答-------------------- 缺少slf4j.jar这个包
补充：Java , Java相关
