java <view-handler>com.sun.facelets.FaceletViewHandler</view-handler>

Question

提问by Princesse

When I add the following line in the faces-config.xml file:

当我在 faces-config.xml 文件中添加以下行时：

" <application><view-handler>com.sun.facelets.FaceletViewHandler</view-handler></application> "

eclipse says:

eclipse 说：

" view-handler references to "com.sun.facelets.FaceletViewHandler" that does not implement interface javax.faces.application.ViewHandler

configure problem severity for preference 'invalid view handler' "

However, I added the libraries in the "lib" of "WEB-INF" of my jsf project. When I deploy my ear and jsf projects, they deploy correctly, but the execution of my jsf page, I get an error:

但是，我在我的 jsf 项目的“WEB-INF”的“lib”中添加了这些库。当我部署我的 ear 和 jsf 项目时，它们部署正确，但是执行我的 jsf 页面时，我收到一个错误：

" javax.servlet.ServletException: /AddUser.xhtml @9,9 <h:head> Tag Library supports namespace: http://java.sun.com/jsf/html, but no tag
was defined for name: head
javax.faces.webapp.FacesServlet.service(FacesServlet.java:606) "

and in the console, I have:

在控制台中，我有：

But when I remove the line in the faces_config.xml: and I redeploy my projects, they are deployed well and my jsf page opens. When I validate the form so that it records in the database, it returns me the same page and in the console, there is the following error:

但是当我删除 faces_config.xml: 中的行并重新部署我的项目时，它们部署良好并且我的 jsf 页面打开。当我验证表单以使其记录在数据库中时，它返回相同的页面，并且在控制台中，出现以下错误：

I do not understand what is happening.

我不明白发生了什么。

It look like that you're mixing JSF 1.x, Facelets 1.x and JSF 2.x. You've there a JSF 2.0 compatible faces-config.xmlroot declaration, but you're still declaring managed beans and navigation cases the legacy JSF 1.x way (those entries are not needed anymore in JSF 2.x thanks to the @MangedBeanannotation and implicit navigation feature). Perhaps you were reading wrong books/tutorials/resources while attempting to learn JSF 2.x.

看起来您正在混合 JSF 1.x、Facelets 1.x 和 JSF 2.x。您有一个兼容 JSF 2.0 的faces-config.xml根声明，但您仍在以旧的 JSF 1.x 方式声明托管 bean 和导航案例（由于@MangedBean注释和隐式导航功能，JSF 2.x 中不再需要这些条目） . 也许您在尝试学习 JSF 2.x 时阅读了错误的书籍/教程/资源。

Also, the ViewHandlerimplementation which you mentioned there is from Facelets 1.x which is only necessary when you're still using the legacy JSF 1.x. However, since JSF 2.x, Facelets 2.x is bundled in the JSF API/implementation JARs and has become the default view technology, thus there is no need to have a separate Facelets JAR file nor to manually register its view handler in faces-config.xml.

此外，ViewHandler您提到的实现来自 Facelets 1.x，只有在您仍在使用旧版 JSF 1.x 时才需要。但是，从 JSF 2.x 开始，Facelets 2.x 捆绑在 JSF API/实现 JAR 中并成为默认视图技术，因此无需单独的 Facelets JAR 文件，也无需在faces-config.xml.

The tag error on <h:head>also confirms that you're actually using JSF 1.x JARs during runtime instead of JSF 2.x as the <h:head>was introduced in JSF 2.x and absent in JSF 1.x.

上的标记错误<h:head>还确认您实际上在运行时使用的是 JSF 1.x JAR，而不是 JSF 2.x，因为 JSF 2.x<h:head>中引入了 JSF 1.x 中不存在的 JSF 2.x。

Get rid of all JSF 1.x and Facelets 1.x related JARs and make sure that you've downloaded and installed the JSF 2.x ones (or just don't download any as JBoss 6x by itself already ships with JSF 2.x bundled, so effectively having a completely empty /WEB-INF/libshould also be sufficient in order to get JSF 2.x to run). Throw away those JSF 1.x books/tutorials/resources and head to JSF 2.x ones. Our JSF wiki pageis a good starting point.

摆脱所有与 JSF 1.x 和 Facelets 1.x 相关的 JAR，并确保您已经下载并安装了 JSF 2.x 的 JAR（或者只是不要下载任何，因为 JBoss 6x 本身已经随 JSF 2.x 提供）。 x 捆绑，因此有效地完全空/WEB-INF/lib也应该足以让 JSF 2.x 运行）。扔掉那些 JSF 1.x 书籍/教程/资源，转向 JSF 2.x。我们的 JSF wiki 页面是一个很好的起点。

As to the XML configuration files, ultimately, you should end up with an emptyfaces-config.xmland onlythe following entry in web.xml:

至于 XML 配置文件，最终，您应该在中得到一个空的faces-config.xml并且只有以下条目web.xml：

<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>

Add if necessary the PrimeFaces theme back, if the default of "aristo" isn't what you want.

如果“aristo”的默认值不是您想要的，则在必要时添加 PrimeFaces 主题。
