環境：Struts 1.3.8 + Spring 2.5.4 ＋ tiles 1.3.8  分多模組

web.xml的配置資訊：

<init-param>

<param-name>config</param-name>

<param-value>/WEB-INF/struts-config/struts-config-default.xml</param-value>

</init-param>

<init-param>

<param-name>config/user</param-name>

<param-value>/WEB-INF/struts-config/user/struts-config-user.xml</param-value>

</init-param>

struts-config-default.xml的Tiles Plug Ins Configuration配置如下：

<plug-in className="org.apache.struts.tiles.TilesPlugin">

<set-property property="definitions-config"  value="/WEB-INF/classes/tiles-def/tiles-defs-default.xml" />

<set-property property="definitions-debug" value="2" />

<set-property property="definitions-parser-details" value="2" />

<set-property property="definitions-parser-validate" value="true" />

<set-property property="moduleAware" value="false" />

</plug-in>

或者

<plug-in className="org.apache.struts.tiles.TilesPlugin">

<set-property property="definitions-config" value="/WEB-INF/classes/tiles-def/tiles-defs-default.xml" />

</plug-in>

程式都會丟擲的下面的異常資訊：

解決方案：

<plug-in className="org.apache.struts.tiles.TilesPlugin">

<set-property property="definitions-config" value="/WEB-INF/classes/tiles-def/tiles-defs-default.xml" />

<set-property property="definitions-debug" value="2" />

<set-property property="definitions-parser-details" value="2" />

<set-property property="definitions-parser-validate" value="true" />

<set-property property="moduleAware" value="true" />    <<---這邊改為true

</plug-in>
