struts 问题

不action 就是你在提交登录表单的时候没指定是哪个action

你的struts.xml文件配置你的action没有？
把你的配置帖出来

补楼上，jsp中的form标签对应的action=。。对应的地址，

谢谢大家给我回复，我现在把代码贴出来，请大家指教．期待回复

把action=="/loginAction.do" 前面的斜线去掉或者在斜线前面在加上项目名，在客户端解释相对地址是以服务器作为基准的，所以你以后在填写路径的时候，要么全部填写完整要么只写***.do，都能正确解释。你报的的应该是404错误~~~

你学得是struts1吧，开始学struts2吧

我把／去掉

错误信息：

        }         throw new java.lang.UnsupportedOperationException(

    }
} 你这里始终抛出了异常把这句话给去掉：

throw new java.lang.UnsupportedOperationException(
                "Method $execute() not yet implemented.");

throw new java.lang.UnsupportedOperationException(
"Method $execute() not yet implemented.");
=========================================
这个是你自己代码里面抛出来的异常阿，基础都没打好就学struts...
