解决方案
解决方案二：
你可以把你的struts.xml贴出来看一下吗？
解决方案三：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"
"http://struts.apache.org/dtds/struts-2.1.7.dtd">
<!-- 文档 -->
<!-- 卡查询 -->
<!-- 监控 -->
<!-- 警报 -->
<!-- 首页数据 -->
<!-- 终端管理 -->
解决方案四：
**<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"
"http://struts.apache.org/dtds/struts-2.1.7.dtd">
<!-- 文档 -->
<!-- 卡查询 -->
<!-- 监控 -->
<!-- 警报 -->
<!-- 首页数据 -->
<!-- 终端管理 -->
**
解决方案五：
无意冒犯，我想看的是你struts.xml里报错的那个action标签
解决方案六：
还是你struts.xml里本来就没有配action?
解决方案七：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
/index.jsp
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
/index.jsp
一般的struts.xml里都像我写的例子里一样要配个action。action的name是访问路径。像我这个例子里，就是访问helloworld.action会进入hello.HelloAction这个文件里默认的execute方法。如果方法里有return success,会转发进入index.jsp里面。第一次回答问题。请多包涵
解决方案八：
原来是发不出来，抱歉。
package name="hello" extends="struts-default"
action name="helloworld" class="hello.HelloAction"
result name="success" /index.jsp result
/action
/package
解决方案九：
看下你配的这个路径/JuiceDemo
