????? <action name="reportAction"
???????? class="com.chinadcl.ReportAction">
???????? <result name="success">reportAction.jsp</result>
????? </action>
????? <action name="ajaxReport"
???????? class="com.chinadcl.AjaxReport">

二、再看AjaxReport.java
注意：這里從ajax傳進來的xml文件如下：

<report>
<path>
d:/country.xml</path>
<parameter>'South America'</parameter>
</report>

package com.chinadcl;

//? 因為在這里生產(chǎn)的報表直接返回給ajax前臺，所以在xwork.xml中不需要配置返回結(jié)果，因為根本不調(diào)用。
