Answer 1

你的方法执行后返回的forward找不到对应的配置。debug一下看看action返回的值，然后看看struts配置文件中有没有对应的forward配置

Answer 2

是不是数据库中的数据没有获取到或者是表单里的数据没有得到

Answer 3

抛空指针异常啊

Answer 4

报的是找不到方法，你有用到jboss，对应的包导入了没，出错应当不是业务代码，而是
SessionFactory
sessionFactory
=
HibernateSessionFactory.getSessionFactory();
貌似就开始出问题了

Answer 5

是不是你forward写错了。？对应的action下下没有该forward？仔细查查看吧
