我正在为我的项目使用 struts2+hibernate 集成，并在其中实现了磁贴，但遇到了这个问题

我在项目中使用的库列表

在此处输入图像描述

这是我尝试访问http://localhost:8080/Struts2HibernatePagination/tigerMenu.action 后的快照

有人可以告诉我为什么我得到这个异常，因为我从过去 2 天开始就被这个问题困扰着，并且尝试了很多改变各种库但没有任何效果！！..请帮助！:(

我已将库替换为

  1. struts2-tiles-plugin-2.1.6.jar
  2. 瓷砖-api-2.1.2.jar
  3. 瓷砖-compat-2.1.2.jar
  4. 瓷砖核心2.1.2.jar
  5. 瓦片-jsp-2.1.2.jar
  6. 瓷砖-servlet-2.1.2.jar

它奏效了！

它不适用于瓷砖 2.2 罐子
