请教struts1x的dispatchAction问题
用struts1做开发,配置如下:
web。xml:
 
  <!-- 配置struts -->
  <servlet>
   <servlet-name>struts</servlet-name>
   <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
   <init-param>
   <param-name>config</param-name>
   <param-value>/WEB-INF/struts-config.xml</param-value>
   </init-param>
   <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
   <servlet-name>struts</servlet-name>
   <url-pattern>*.do</url-pattern>
  </servlet-mapping>
  
 </web-app>


struts-config.xml:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd">

<forward name="err" path="/WEB-INF/login.jsp" />
</action>
</action-mappings>
</struts-config>
login。jsp:
<body>
<h1>管理员登陆</h1>
<form action="/myssh/login.do?method=login" method="POST">
