Struts2的jQuery插件抛出java.lang.ClassNotFoundException

问题是有关的Struts v2.3.16和Struts2的jQuery插件v3.6.1。 它看起来像Struts的项目不支持第三方插件，像Struts2的jQuery插件。如何解决以上版本的不兼容？这是扔在启动时的异常

Answer 1:

请使用Struts2的jQuery插件的最新版本3.7.0。这个版本是2.3.16的Struts兼容。

见Struts2的jQuery插件更新日志了解更多详情。

Answer 2:

由于Struts的2.3.16的有没有更多的接口org.apache.struts2.views.TagLibrary 。

你应该总是使用最新版本的插件。
