JSF tags are not being rendered
提问by Dan Prince
I'm starting a JSF project (this is the first time I've used JSF) and I'm having problems with the tags being rendered. I'm developing in Eclipse and using TomCat as a server.
我正在启动一个 JSF 项目（这是我第一次使用 JSF）并且我在渲染标签时遇到了问题。我正在 Eclipse 中开发并使用 TomCat 作为服务器。

I am accessing the file with this url: http://localhost:8080/DeutschAkademie/login.jspand
as I understand the <h:form>tag should render as <form>, but instead it's instead rendering as <h:form>. Any ideas?
我正在使用这个 url 访问文件：http://localhost:8080/DeutschAkademie/login.jsp据我所知，<h:form>标签应该呈现为<form>，但它反而呈现为<h:form>. 有任何想法吗？

Two advices:
两个建议：
Update the URL pattern for Faces Servlet. The default configuration can be for
*.jsp(no need to use*.facesor something else. Still, I would recommend using*.xhtml.JSF 2 works with Facelets, so you don't need to use old JSP anymore. By reading your login.jsp page content, you can just rename the extension from jsp to xhtml and it will work.
更新 Faces Servlet 的 URL 模式。默认配置可以是
*.jsp（不需要使用*.faces或其他东西。不过，我建议使用*.xhtml.JSF 2 与 Facelets 一起工作，因此您不再需要使用旧的 JSP。通过阅读您的 login.jsp 页面内容，您只需将扩展名从 jsp 重命名为 xhtml 即可。
Based on these, the web.xmlwill look like this:
基于这些，web.xml将如下所示：
<web-app>
<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>*.xhtml</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>login.xhtml</welcome-file>
</welcome-file-list>
</web-app>
And having login.xhtmlfile.
并有login.xhtml档案。
To access to your page you will only need to write http://localhost:8080/DeutschAkademie/login.xhtmlin your browser address bar.
要访问您的页面，您只需要http://localhost:8080/DeutschAkademie/login.xhtml在浏览器地址栏中输入即可。

EDIT:
编辑：
Based on the picture of your project, the WEB-INF/libfolder is clean. You should drop the JSF 2 libraries there. Add them, recompile your project and try it again.
根据您项目的图片，WEB-INF/lib文件夹是干净的。您应该将 JSF 2 库放在那里。添加它们，重新编译您的项目并重试。

When you create your project, the web.xmlwill be generated for you and as default the servlet-mappinginside of this file will look like that:
当您创建项目时，web.xml将为您生成 并且默认情况下servlet-mapping，此文件的内部将如下所示：
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
It expect that you will put all your.xhtmlfiles under a folder called faces.
So you can create this folder called facesunder WebContentand put your .xhtmlfiles there and than call your application http://localhost:8080/DeutschAkademie/faces/login.xhtml
Or you can edit your web.xmland change the servlet-ammping to
它希望您将所有.xhtml文件放在一个名为faces.
所以你可以创建这个名为facesunder 的文件夹WebContent并将你的.xhtml文件放在那里，然后调用你的应用程序http://localhost:8080/DeutschAkademie/faces/login.xhtml
或者您可以编辑您的web.xml并将 servlet-ampping 更改为
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
and than call your application http://localhost:8080/DeutschAkademie/login.xhtml
Those Solutions have also been mentioned above.
而不是调用您的应用程序http://localhost:8080/DeutschAkademie/login.xhtml
上面也提到了这些解决方案。

After addding <url-pattern>*.xhtml</url-pattern>, ensure your files have extension .xhtml, otherwise will not work.
添加后<url-pattern>*.xhtml</url-pattern>，确保您的文件扩展名为.xhtml，否则将无法工作。
