Answer 1

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled()Z
应该是包的问题吧，有没有将log4j的包导入进来。。
查了下资料，有的人说重装下Tomcat就可以了，不知是真是假。。
------------------------------------------------------------------------------------------------------在一个，你好像前面也有错误也。
hibernate.properties not found
Configured SessionFactory: null
检查下hibernate包导入进来没有，配置文件是否写对了

Answer 2

楼上的我照着你的方法做了还是没有解决问题，重装了下Tomcat，hibernate包导入进来！再出个主意吧？
