JSF 配置的 jsp 文件是运行，但 xhtml 不是运行

Question

我已经尝试了在 Whosebug 和其他论坛上看到的所有内容。没用。

运行 jsp 文件是正确的，但不是 xhtml 页面的新 facelets。

我关注了从 jsf1.x 到 2.x 的迁移线程：Migrating from JSF 1.2 to JSF 2.0

甚至过滤器也可以在简单的 jsp 实现中工作，在这里我尝试删除过滤器，它仍然无法工作。甚至无法找出错误。

错误：

Answer 1

自己解决了。必须完全清空 faces-config.xml 文件，该文件以前填充了 managedBeans。

而且 xhtml 文件中的 ui:composition 标记也被删除，我认为这是主要问题。

Answer 2

我遇到了同样的问题。经过调查，我发现您提到的问题与 ui:composition 标签有关。它给出该错误的原因是没有定义模板文件。一旦我定义了一个，它就可以正常工作。
