Tiles定义可以使用Spring TileConfigure扩展外部jar中定义的定义吗？

库版本：Spring 3.1.2，Tiles 2.2.2

给定以下设置，是否可以从外部（common.jar）扩展和使用磁贴定义（即下面的“BaseTile”）

common.jar

/WEB-INF/common-tiles-defs.xml

任何帮助都将不胜感激

多谢各位

<tiles-definitions>

    <definition name="BaseTile" template="/WEB-INF/tiles/BaseTile.jsp">
        <put-attribute name="content" value="" />
    </definition>

</tiles-definitions>

<tiles-definitions>

    <definition name="ProjectTile" extends="BaseTile">
        <put-attribute name="content" expression="${someData}" />
    </definition>

</tiles-definitions>
