  1.   

    404就是找不到 指定的页面
    你可以看一下form表单对应的action路径是否正确
    如果报错找不到对应的action，可参考下面文章修改
    点这里

  3.   

    是我struts.xml配置不对么？错误信息贴在楼上了，能不能帮忙看一下？谢谢你
      

  4.   

    解决的办法是把struts2-blank-2.2.1.war示例工程中的web-inf/lib下的javassist-3.7.ga.jar拷贝出，加入你的工程中即可！
      

  5.   

    看下文能不能解决
    http://blog.csdn.net/sbangm/article/details/6912438
      

  6.   

    刚才有个朋友已经建议过了，我也贴在lib里了但还是不行......
      

  7.   

    已经解决了，少加了commons-fileupload-1.2.1.jar这个包，谢谢各位了
      

  8.   

    默认拦截器栈，struts2框架底层用到的fileupload.jar
      

  9.   

    struts.xml在src目录下，你那个result的跳转页面错了！
