web.xml写的是 index.jhtml 但是里面什么也没有  他怎么提交到Action里的....

您看的是安装前的web.xml吧

<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.shtml</welcome-file>
<welcome-file>index.jhtml</welcome-file>
</welcome-file-list>
                   不是是安装后的
系统都能跑起来

安装后的是

对 就是这个  我只是想知道他是怎么跳的  index.jhtml什么也没啊

其他的配置文件，您看一下

具体在那个配置文件里

这个得您自己看的，代码如何运作是不进行解释分析的哦
