JSP+struts+hibernate开发在线考试管理系统时出错，请高手帮忙！！！
现在程序能进入运行界面，当相应的用户进入各用户功能界面后，进行下一步的功能操作时出错下面的错误：
type Exception report

description The server encountered an internal error () that prevented it from fulfilling this request.

javax.servlet.ServletException: Couldn't find the role!
cn.hxex.exam.filter.HibernateFilter.doFilter(HibernateFilter.java:71)
root cause
cn.hxex.exam.exception.ExamSystemException: Couldn't find the role!

cn.hxex.exam.filter.HibernateFilter.doFilter(HibernateFilter.java:49)
请问各位高手出错的原因是什么原因，是不是因为创建的数据表出错的原因！！
[解决办法]
是因为你没有在配置文件中给这个角色赋权限．
在你的．ＸＭＬ配置文件中，有一个ＡＣＴＩＯＮ方法没有注册这个方法权限吧
cn.hxex.exam.filter.HibernateFilter.doFilter(HibernateFilter.java:71)
在这个方法里，是你们自己封装了．没有给这些用户权限．所以都进不去
[解决办法]
最好把代码格式一下
