    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.
    Default is 'true'</description>

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

    If true, a javascript function will be rendered that is able to restore the

    if you trigger a link or button action that stays on the same page.

That's not a problem. That's expected behaviour. You're just misunderstanding how the basic Servlet API works. You have configured the JSF-standard FacesServletto listen on URLs matching /faces/*and you have configured Apache MyFaces specific MyFacesServletto listen on URls matching *.jsfand *.faces.

那不是问题。这是预期的行为。您只是误解了基本 Servlet API 的工作原理。您已将 JSF 标准配置FacesServlet为侦听 URL 匹配，/faces/*并且已将 Apache MyFaces 配置为特定MyFacesServlet于侦听 URls 匹配*.jsf和*.faces.

To get JSF to run, you have to open the page in browser by an URL which matches the mapping of the FacesServlet. Given the fact that you've an index.jspfile and that your context path is Graphand that you have configured two JSF servlets on three different URL patterns, you can open the JSP by the following URLs:

要运行 JSF，您必须在浏览器中通过匹配 .js 文件映射的 URL 打开页面FacesServlet。鉴于您有一个index.jsp文件并且您的上下文路径是Graph并且您已经在三种不同的 URL 模式上配置了两个 JSF servlet，您可以通过以下 URL 打开 JSP：

• http://localhost:8080/Graph/faces/index.jsp(invokes FacesServlet)
• http://localhost:8080/Graph/index.jsf(invokes MyFacesServlet)
• http://localhost:8080/Graph/index.faces(invokes MyFacesServlet)

• http://localhost:8080/Graph/faces/index.jsp（调用FacesServlet）
• http://localhost:8080/Graph/index.jsf（调用MyFacesServlet）
• http://localhost:8080/Graph/index.faces（调用MyFacesServlet）

Said that, your configuration is unnecessarily overcomplicated. Get rid of the MyFacesServletentry and all of its associated URL mappings (with the servlet name of faces). Just stick to the standard FacesServletand use its mapping instead, or alter it instead. I personally recommend using *.jsf.

就是说，你的配置不必要地过于复杂。删除MyFacesServlet条目及其所有关联的 URL 映射（servlet 名称为faces）。只需坚持标准FacesServlet并使用其映射，或者改为更改它。我个人建议使用*.jsf.

<servlet>
    <servlet-name>facesServlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>facesServlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>

Then you can just open the page by http://localhost:8080/Graph/index.jsf.

然后你可以通过http://localhost:8080/Graph/index.jsf打开页面。

Unrelated to the concrete problem, your welcome-filewon't work that way. Tomcat would give a HTTP 404 error on that (page/resource not found). You need to specify index.jsfas welcome-fileand supply a concrete but emptyindex.jsffile in the same folder as your index.jsp. This way Tomcat will be fooled that the file exist and show the page by just calling http://localhost:8080/Graph.

与具体问题无关，你welcome-file不会那样工作。Tomcat 会给出一个 HTTP 404 错误（页面/资源未找到）。你需要指定index.jsf的welcome-file，并提供一个具体的，但空index.jsf在同一文件夹中文件index.jsp。这样 Tomcat 就会被愚弄，认为该文件存在并通过调用http://localhost:8080/Graph 来显示页面。

If your concern is that it is possible to open JSF pages by their *.jspextension which would result in a RuntimeException: FacesContext not foundand you have actually no one JSP file which is to be served plain vanilla, then you can restrict direct access to JSP files by the following security constraint in web.xml:

如果您担心有可能通过*.jsp扩展名打开 JSF 页面，这会导致RuntimeException: FacesContext not found您实际上没有一个 JSP 文件可以提供普通的普通版本，那么您可以通过以下安全约束来限制对 JSP 文件的直接访问在web.xml：

<security-constraint>
    <display-name>Restrict direct access to JSP files</display-name>
    <web-resource-collection>
        <web-resource-name>JSP files</web-resource-name>
        <url-pattern>*.jsp</url-pattern>
    </web-resource-collection>
    <auth-constraint />
</security-constraint>

(in JSF 2.0 this is by the way not needed anymore, with the default view technology Facelets it's possible to map the FacesServleton just *.xhtml, which is the same as the default extension of Facelets files)

（顺便说一下，在 JSF 2.0 中，这不再需要了，使用默认的视图技术 Facelets 可以映射FacesServleton just *.xhtml，这与 Facelets 文件的默认扩展名相同）

you can deploy your application with the tomcat manager

您可以使用 tomcat 管理器部署您的应用程序

http://tomcatIP:8080/manager/html

http://tomcatIP:8080/manager/html

there you can upload your application and it should run out of the box if you have no idea what username and password you should type in, you have to configure your tomcat-users.xml

在那里你可以上传你的应用程序，如果你不知道应该输入什么用户名和密码，它应该开箱即用，你必须配置你的 tomcat-users.xml
