父包未定義：jfreechart默認[未知位置]

我想使用Struts2 jfreechart插件 - 使用Maven項目。在Maven依賴關係中，我能夠看到jfree-chart jar文件。父包未定義：jfreechart默認[未知位置]

我需要使用單獨的包嗎？

任何人都可以幫忙嗎？

獲得以下錯誤：

在struts.xml你已經使用了需要struts2-jfreechart-plugin-x.x.x.jar是在類路徑中的代碼。這個插件有struts-plugin.xml，其中jfreechart-default包被定義。如果您的包裹延伸jfreechart-default，則需要this。

<package name="basicstruts2" extends="struts-default, jfreechart-default">

非常感謝Roman.Earlier我只添加了jfreechart神器。添加struts2-jfreechart-plugin工件依賴關係後 - 完美工作。 – 2015-03-14 09:43:51
