action

Answer 1

页面请求地址对了的 /ST/stu/showStu.action
ST是项目名 /stu是namespace
我的struts.xml没有放在src下面 但是我web。xml里面配置正确了的
能够读取到，为什么总是报这个错误啊求解！！！

Answer 2

你可以试着将xml文件放在src目录下再测试呢？

Answer 3

1、你路径写的有问题
2、你没有配置这个action

Answer 4

<servlet>
        <servlet-name>action</servlet-name>
        <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>        <!-- Default -->
        <init-param>
            <param-name>config</param-name>
            <param-value>/WEB-INF/struts-config.xml</param-value>
        </init-param>        <!-- stumodule -->
        <init-param>
            <param-name>config/stu</param-name>
            <param-value>/WEB-INF/stu/struts-config.xml</param-value>
        </init-param>
       <load-on-startup>2</load-on-startup>
    </servlet>

Answer 5

There is no Action mapped for namespace /stu and action name showStu
按你说的，配置在web.xml中了，但是有没有加载或加载成功呢
这个错误就是告诉你在命名空间/stu中找不到action showStu
多数配置加载有问题
