[异常]在Tiles中我用Definition in jsp page方式时，用extends时异常，同志们帮看看，谢了！

据项目需求：我需要在jsp程序中动态定义Tiles的definition.
经过测试当我不使用extends或者<tiles:put name="body" value="strongpp.wangshang.body" />
这样的转到别一个definition（如：strongpp.wangshang.body）时程序正常运行。或者我使用tiles-defs.xml
这样的配置文件定义时，程序都是正常运行。

使用了extends和<tiles:put name="body" value="strongpp.wangshang.body" />的程序及配置如下:
我的definition的JSP程序如下：
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>

<tiles:definition id="strongpp.portal.masterPage" page="/layouts/classicLayout.jsp" >
<tiles:put name="titles" value="Tiles 1.1 Examples" />
<tiles:put name="header" value="/portal/wangshang/common/header.jsp" />
<tiles:put name="footer" value="/portal/wangshang/common/footer.jsp" />
<tiles:put name="body" value="/portal/wangshang/common/body.jsp" />
</tiles:definition>

<tiles:definition extends="strongpp.portal.masterPage" id="strongpp.wangshang.mainLayout">
<tiles:put name="titles" value="12345网上受理" />
<tiles:put name="header" value="/portal/wangshang/common/header.jsp" />
<tiles:put name="body" value="strongpp.wangshang.body" />
<tiles:put name="footer" value="/portal/wangshang/common/footer.jsp" />
</tiles:definition>

<tiles:definition controllerUrl="/portal/myPortal.do" id="strongpp.wangshang.body" page="/layouts/cloumslayout.jsp" >
<tiles:put name="numCols" value="2" />
<tiles:putList name="list0">
<tiles:add value="/portal/wangshang/reXianZaiBao.jsp" />
<tiles:add value="/portal/wangshang/shouLi.jsp" />
<tiles:add value="/portal/wangshang/downloads.jsp" />
</tiles:putList>
<tiles:putList name="labels0">
<tiles:add value="热线摘报" />
<tiles:add value="网上受理" />
<tiles:add value="下载中心" />
</tiles:putList>
</tiles:definition>

使用的JSP程序index.jsp如下所示：
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<%@ include file="/WEB-INF/definitions/definition.jsp"%>
<html>
<head>
<title>
index2
</title>
</head>
<body bgcolor="#ffffff">
<tiles:insert beanName="strongpp.wangshang.body" beanScope="request"/>
</body>
</html>

异常：

呵呵，知道了~~在struts.conf里加入：

<plug-in className="org.apache.struts.tiles.TilesPlugin" >
<set-property property="definitions-config"
value="/WEB-INF/tiles-defs.xml" />
<set-property property="moduleAware" value="true" />
</plug-in>
