The XML taglib namespace URI does not point to a real web resource or something. It just points to the same value as the <namespace>entry of the .taglib.xmlfile of the XML taglib in question in the runtime classpath, which in case of JSF taglibs (and lot others) justhappens to be a HTTP URL. In case of Mojarra, you can find the declaration in the /com/sun/faces/metadata/taglib/html_basic.taglib.xmlfile of the jsf-impl.jarfile.
XML taglib 命名空间 URI 并不指向真正的 Web 资源或其他东西。它只是指向相同的值<namespace>在进入.taglib.xml的XML标签库的文件中的问题在运行时类路径，这在JSF标签库（和很多其他人）的情况下，只是恰巧是一个HTTP URL。在 Mojarra 的情况下，您可以在/com/sun/faces/metadata/taglib/html_basic.taglib.xml文件的jsf-impl.jar文件中找到声明。
If you're encountering problems with referencing JSF HTML tags, then the cause lies somewhere else.
如果您在引用 JSF HTML 标签时遇到问题，那么原因就在其他地方。

Previous answers were useful to me. Here I provide an alternative way for solving this issue. I fixed this problem by adding the jar primefaces-[version].jarto the WEB-INF/libdirectory.
以前的答案对我有用。在这里，我提供了一种解决此问题的替代方法。我通过将 jar 添加primefaces-[version].jar到WEB-INF/lib目录中解决了这个问题。
