[解决办法]
jsp可以进去，点提交报404，应该是配置问题，1可能是action的路径，2可能是forward jsp的路径
这两个其中一个配置不对找不到，所以报404，大致看了一下，你可以把jsp的路径写全一些试试
[解决办法]
<package name="package" extends="struts-default" namespace="/huazhaosoft">
你的namespace是在/huazhaosoft下找这个action的。
而你的页面请求的action是
<form name="form1" method="post" action="manager.do?action=login">
按照你struts.xml配置的话 前台的jsp页面的action应该改为
<form name="form1" method="post" action="/huazhaosoft/managerForm.action">
看了看你struts配置 把我写的action变成你的do 试试。
