【中文标题】Richfaces 4 组件不渲染【英文标题】：Richfaces 4 components don't render 【发布时间】：2011-12-23 07:34:25 【问题描述】：

我遇到的问题是 jsf 标签没有被解析，所以我没有在我的页面中看到richfaces 组件。我正在使用 Richfaces 4、tomcat 7 和 jsf 2.0

这是我的 faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>

    This parameter tells MyFaces if javascript code should be allowed in
    the rendered HTML output.
    If javascript is allowed, command_link anchors will have javascript code
    that submits the corresponding form.
    If javascript is not allowed, the state saving info and nested parameters
    will be added as url parameters.

    If true, rendered HTML code will be formatted, so that it is 'human-readable'

我用于测试的示例（我从浏览器得到的源代码是相同的）：

如果有人有一些建议，请写..提前谢谢

【问题讨论】：

XHTML 文件的源代码是什么？ （您不需要发布 1000 行代码；只需尽可能最小的仍然重现此问题的代码就足够了，例如，只有一个 Richfaces 组件）。您在浏览器地址栏中使用的 URL 是什么？浏览器检索到的生成的 HTML 代码是什么？ （在浏览器中右键单击页面，查看源代码）。请编辑您的问题以包含此信息。 感谢您的建议，但我发布了所有内容，因为我真的不知道问题出在哪里。我使用正确的网址（我可以在浏览器中打开页面）。现在我在我的问题中包含了 xHTML 文件。因此，如果您有任何进一步的建议，请告诉我。 【参考方案1】：

我从浏览器得到的源代码是一样的

换句话说，FacesServlet 没有被调用，因此无法完成它的工作。这只能意味着请求 URL 与 FacesServlet 中定义的 URL 模式不匹配 web.xml。也许您是通过 http://localhost:8080/bisis-please-work/somepage.xhtml 而不是 http://localhost:8080/bisis-please-work/somepage.jsf 打开页面，这将匹配您在 web.xml 中定义的 &lt;url-pattern&gt;*.jsf&lt;/url-pattern&gt;。

或者，您也可以将*.jsf 替换为*.xhtml，这样您就不必再摆弄URL，也不必担心客户端能够看到原始JSF 源代码。唯一的缺点是，如果不调用 FacesServlet，您将无法提供“普通的”XHTML 文件，但这没关系，这些文件无论如何都应该具有 .html 扩展名。

【讨论】：

这有帮助。非常感谢。 :) BalusC，你能看看我的问题***.com/questions/8204417/… ..我不确定这是否是与你联系的合适方式，但我发现你的答案解释得很好..提前致谢【参考方案2】：

我遇到了同样的问题，但根本原因不同。对我来说，richfaces 组件，尤其是 rich:tabPanel，没有渲染，因为页面中有普通的 html 标签。

<head>...</head>

而不是

<h:head>...</h:head>

导致rich:tabPanel 根本不显示。

使用纯 html 正文标签会导致选项卡呈现，但不可点击。
