Question

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' "

但是，我在我的jsf项目的“WEB-INF”的“lib”中添加了库。当我部署我的ear和jsf项目时，他们正确部署，但是我的jsf页面的执行，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) "

在控制台中，我有：

但是当我删除faces_config.xml中的行时：我重新部署我的项目，他们部署得很好，我的jsf页面打开。当我验证表单以便它在数据库中记录时，它返回相同的页面并在控制台中，出现以下错误：

我不明白发生了什么。

Answer 1

看起来你正在混合使用JSF 1.x，Facelets 1.x和JSF 2.x.你有一个JSF 2.0兼容的faces-config.xml根声明，但是你仍然使用传统的JSF 1.x方式声明了托管bean和导航案例（由于{{{i}，JSF 2.x中不再需要这些条目{1}}注释和隐式导航功能）。也许你在尝试学习JSF 2.x时读错了书/教程/资源。

此外，您在那里提到的@MangedBean实现来自Facelets 1.x，这仅在您仍在使用旧版JSF 1.x时才需要。但是，由于JSF 2.x，Facelets 2.x捆绑在JSF API /实现JAR中并且已成为默认的视图技术，因此不需要单独的Facelets JAR文件，也不需要在{}中手动注册其视图处理程序。 {1}}。

ViewHandler上的标记错误也确认您实际上在运行时使用JSF 1.x JAR而不是JSF 2.x，因为faces-config.xml是在JSF 2.x中引入的，并且在JSF 1.x。

摆脱所有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（或者只是不下载任何JBoss 6x本身已经随附捆绑了JSF 2.x，因此有效地拥有一个完全空<h:head>也应该足以让JSF 2.x运行）。扔掉那些JSF 1.x书籍/教程/资源，然后转到JSF 2.x版本。 Our JSF wiki page是一个很好的起点。

对于XML配置文件，最终，您应该在<h:head>中输入空 /WEB-INF/lib和以下条目：

faces-config.xml

如果默认的“aristo”不是您想要的，请在必要时添加PrimeFaces主题。

<视图处理程序> com.sun.facelets.FaceletViewHandler </视图处理程序>
