ssh框架下的struts.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
    <package name="default" namespace="/" extends="struts-default">
       <action name="hello" class="edu.cjdx.action.helloAction">
          <result name="success">index.jsp</result>
          <result name="false">add.jsp</result>
          <result name="edit">edit.jsp</result>
       </action>
    </package>
</struts>    

注：

1.400错误多为struts.xml文件配置错误
2.服务器拒绝连接：检查端口，路径
3. Action访问路径： 缺省以.action结尾（即，路径为localhost：端口号/项目名/hello.action） 也可自己配置，如：

<constant name="struts.action.extension" value="action,do,webwork"></constant>

上述配置，将使得可以通过.action或.do或.webwork访问Action对象
