看下你Strut的控制器的Action有没有在web.xml控制器里面配置
<servlet>
    <servlet-name>action</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>
    <init-param>
      <param-name>debug</param-name>
      <param-value>3</param-value>
    </init-param>
    <init-param>
      <param-name>detail</param-name>
      <param-value>3</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
  </servlet>
<servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

Answer 3

如果这部分没问题的话，看下
struts-config.xml 里面配置的
 <action
      input="/test.jsp"
      path="/xindai"
      type="类的名称" >
             </action>看下类的名称是否是正确的，，类要写绝对的路径
