<?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">

<struts>
	<package name="default" extends="struts-default">
		<action name="add" method="add"
			class="com.action.ClassAction">
			<result name="success">/pages/cadastro/index.jsp</result>
		</action>		
	</package>
</struts>
