JSF ui：包括在文件夹中找不到内容答案

【问题标题】：JSF ui:include not finding contents in foldersJSF ui：包括在文件夹中找不到内容
【发布时间】：2014-06-20 14:10:16
【问题描述】：

我正在从 bean 动态设置 JSF 包含：<ui:include src="#{criteriaBean.criteriaPage}" />，如果标准页面位于项目的 WebContent 的根目录上，它就可以正常工作。

出于维护目的，我希望将这些包含文件放在它们自己的文件夹中。

但是，如果我尝试将内容放入文件夹中，无论是在 WebContent 的根目录下还是在 WEB-INF 的内部，请更新 criteriaBean 以使那里的路径看起来正确，然后尝试加载页面，我收到javax.faces.view.facelets.TagAttributeException 指出路径无效。

我什至尝试过不使用 bean 并硬编码一个值来测试：<ui:include src="/WEB-INF/rptCriteria/test.xhtml" /> 和 <ui:include src="/rptCriteria/test.xhtml" />，但我得到了同样的错误。

理想情况下，我希望 WEB-INF 文件夹能够正常工作。

有什么我可能会遗漏的想法吗？

这是完整的堆栈跟踪：

【问题讨论】：

应该可以。查看来自stackoverflow.com/questions/4792862/… 的示例。你能告诉我们项目结构吗？
@loan - 抱歉，从 Apache Wicket 迁移到 JSF，所以我不确定您所说的项目图是什么意思。
对不起，我的意思是项目结构。你能告诉我们整个堆栈跟踪吗？
@loan 我添加了堆栈跟踪
看起来可能是因为 Eclipse 没有将 xhtml 文件保存为 UTF-8。我将xhtml 的默认编码更改为UTF-8 并重新启动Eclipse。这似乎奏效了，但我也尝试了很多其他的东西。我将在周一尝试用另一个有同样问题的项目重新创建它。

标签： jsf jsf-2

【解决方案1】：

根本问题似乎与 Eclipse 没有为 xhtml 文件设置默认编码这一事实有关。即使个别文件以<?xml version="1.0" encoding="UTF-8" /> 开头 - 当文件部署到 JBoss EAP 6.1 时，还是有问题。

我更新了 Eclipse (Window -> Preferences -> General + Content Types + Text) 以确保所有 xhtml 文件的默认编码设置为 UTF-8，在重新启动 Eclipse 并重新部署到代码后，异常消失了，现在一切正常.

这也在另一台机器上得到验证。
