The symptoms of the JSF components not being parsed at all indicates that the FacesServlethasn't run. This will happen when the request URL doesn't match the url-patternof the FacesServletas definied in web.xml. This would mean that the actualurl-patternof the FacesServletisn't *.xhtmlat all. Are you looking into and editing the right web.xmlyou think you are? Is the right web.xmlbeen deployed with the webapp into the servletcontainer?
根本没有解析 JSF 组件的症状表明FacesServlet尚未运行。当请求URL不匹配，这会发生url-pattern的FacesServlet，如definied web.xml。这将意味着根本不是实际url-pattern的。您是否正在研究和编辑您认为的权利？权限是否已随 webapp 部署到 servletcontainer 中？FacesServlet*.xhtmlweb.xmlweb.xml

Man, you haven't set the javax.faces.DEFAULT_SUFFIXcontext parameter. The default for jsfis jsp, so jsfwill search for example.jspinstead of example.xhtml. Basically JSFreplaces the extension of the resource requested with the javax.faces.DEFAULT_SUFFIX.
伙计，你还没有设置javax.faces.DEFAULT_SUFFIX上下文参数。默认jsf就是jsp，这样jsf将搜索example.jsp代替example.xhtml。基本上JSF用javax.faces.DEFAULT_SUFFIX.
Use the following and it will work:
使用以下内容，它将起作用：
<context-param>
<param-name>javax.faces.DEFAULT_SUFFIX</param-name>
<param-value>.xhtml</param-value>
</context-param>

Do you have faces-config.xml in place that declares Facelets as view handler?
您是否有将 Facelets 声明为视图处理程序的 faces-config.xml？
<?xml version="1.0"?>
<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd" version="1.2">
<application>
<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
</application>
</faces-config>
Don't forget about javax.faces.DEFAULT_SUFFIX parameter to be set to .xhtml as mentioned above.
不要忘记将 javax.faces.DEFAULT_SUFFIX 参数设置为 .xhtml 如上所述。

Add the following in your web-inf/lib :
在您的 web-inf/lib 中添加以下内容：
jsf-api-2.0.9.jar jsf-facelets-1.1.14.jar jsf-impl-2.0.4-b09.jar jstl-1.2.jar
jsf-api-2.0.9.jar jsf-facelets-1.1.14.jar jsf-impl-2.0.4-b09.jar jstl-1.2.jar
without jsf-facelets*.jar, you won't be able to render the jsf view.
如果没有 jsf-facelets*.jar，您将无法呈现 jsf 视图。
And, following should be in your web.xml :
并且，以下应该在您的 web.xml 中：
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/jsf/*</url-pattern>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
Without above two url-pattern, tomcat won't be able to map .xhtml file properly.
如果没有以上两个 url-pattern，tomcat 将无法正确映射 .xhtml 文件。
And, faces-config.xml :
而且，faces-config.xml ：
<?xml version="1.0" encoding="UTF-8"?>
<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">
</faces-config>
