jsf2 xhtml 页面不被浏览器解释

发布于 2024-12-11 12:06:38 字数 2990 浏览 0 评论 0原文

我正在测试 coreservlets 站点上的应用程序“jsf-blank”，以便了解 jsf 的工作原理，但我的浏览器不显示 xhtml 页面的内容。

我使用 Tomcat 6 和 Eclipse Indigo。

您知道为什么我的浏览器中的页面是空白的吗？

感谢您的帮助。

谢谢，但它不适用于 jsp 指令，这是我的 web.xml 的内容：

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>
<context-param>
    <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
    <param-value>.xhtml</param-value>
</context-param>
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
</welcome-file-list>

最后更新：

我尝试了你的解决方案，但我有同样的问题，jsf 标签不是由浏览器渲染的（我是 JSF 的新手）。

我的测试非常简单：

web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"                             xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
  http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>
<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
</welcome-file-list>

index.xhtml ：

  <!DOCTYPE html>
  <html lang="en"
     xmlns="http://www.w3.org/1999/xhtml"
     xmlns:f="http://java.sun.com/jsf/core"
     xmlns:h="http://java.sun.com/jsf/html"
     xmlns:ui="http://java.sun.com/jsf/facelets">
     <h:head>
       <title><h:outputText value="First JSF Application" /></title>
     </h:head>
     <h:body>
        <h:outputText value="Test" /> 
     </h:body>
   </html>

上下文名称：jsf-blank

我使用 url 进行测试： http://localhost:8080/ jsf-blank/index.xhtml

结果：空白页

最后更新：

谢谢，我的问题解决了，我认为问题的根源是 rich-faces 3.3 jars我的tomcat的文件夹shared/lib。

我删除了这些罐子，现在它可以工作了，你知道为什么会出现问题吗？

I am testing the application "jsf-blank" from coreservlets site in order to understand how jsf works but my browser doesn't show the content of the xhtml page.

I use Tomcat 6 and Eclipse Indigo.

Have you any idea why the page is blank in my browser ?

Thank you for your help.

Thank you but it doesn't work with jsp directive and this is the content of my web.xml :

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>
<context-param>
    <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
    <param-value>.xhtml</param-value>
</context-param>
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
</welcome-file-list>

Last update :

I tried your solutions but I have the same problem, jsf tags aren't rendered by browser (I am a newbie in JSF).

My test is very simple :

web.xml :

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"                             xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
  http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>
<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
</welcome-file-list>

index.xhtml :

  <!DOCTYPE html>
  <html lang="en"
     xmlns="http://www.w3.org/1999/xhtml"
     xmlns:f="http://java.sun.com/jsf/core"
     xmlns:h="http://java.sun.com/jsf/html"
     xmlns:ui="http://java.sun.com/jsf/facelets">
     <h:head>
       <title><h:outputText value="First JSF Application" /></title>
     </h:head>
     <h:body>
        <h:outputText value="Test" /> 
     </h:body>
   </html>

Context name : jsf-blank

I test with url : http://localhost:8080/jsf-blank/index.xhtml

Result : blank page

Last update :

Thank you, my problem is solved, I think the origin of problem was rich-faces 3.3 jars in my tomcat's folder shared/lib.

I removed these jars and now it's working, do you know why it's a problem ?

当您发送的请求的 URL 与 FacesServlet 的 URL 模式不匹配时，就会发生这种情况，从而导致 JSF 工作根本无法运行。根据 servlet 映射的 URL 模式，您必须请求带有 .jsf 扩展名的 XHTML 页面。假设您有一个 index.xhtml，那么您需要通过 http:// 调用它本地主机：8080/contextname/index.jsf。

不过，我建议将 *.jsf URL 模式替换为 *.xhtml，这样您就无需担心和摆弄后缀。更改您的 web.xml 如下：

<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

<welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
</welcome-file-list>

并通过 http://localhost:8080/contextname/ 打开页面索引.xhtml。

That can happen when you have sent a request whose URL does not match the URL pattern of the FacesServlet which in turn causes that the JSF works won't run at all. According to the URL pattern of your servlet mapping, you have to request your XHTML page with .jsf extension. Imagine that you've an index.xhtml, then you'd need to invoke it by http://localhost:8080/contextname/index.jsf.

I however recommend to just replace the *.jsf URL pattern by *.xhtml so that you never need to worry about and fiddle with suffixes. Change your web.xml as follows:

<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
</context-param>

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

<welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
</welcome-file-list>

And open the page by http://localhost:8080/contextname/index.xhtml.
