<?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><constant name="struts.objectFactory" value="spring" /><constant name="struts.enable.DynamicMethodInvocation" value="true" /> <constant name="struts.devMode" value="true" /> <constant name="struts.i18n.reload" value="true" /> <constant name="struts.configuration.xml.reload" value="true" /> <constant name="struts.custom.i18n.resources" value="globalMessages" /> <constant name="struts.url.includeParams" value="none" /> <constant name="struts.ui.theme" value="xhtml"></constant> <package name="struts2" extends="struts-default"> <default-action-ref name="clasquery"></default-action-ref> <action name="clasquery" class="clasQueryAction"> <result name="success">/query.jsp</result> </action> <action name="clas" class="clasAction"> <result name="success" type="redirect">/clasquery.action</result> </action> </package></struts>
