我正在尝试运行一个简单的 JSF（基于 PrimeFaces）应用程序。

主页面非常简单：

<?xml version="1.0"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

        xmlns:h="http://java.sun.com/jsf/html"
        xmlns:p="http://primefaces.org/ui">
<head>
<title>Hello World</title>
</head>
<body>
        <p:editor />
</body>
</html>

当我

  1. 尝试使用mvn jetty:run和运行 Web 应用程序
  2. 在浏览器中打开页面，

我收到以下错误：

代码位于https://dl.dropbox.com/u/11776689/2012_09_29_primefaces_app.zip。

我该如何解决这个错误？

更新1：

根据 BalusC 的建议，我注释掉了依赖项

<dependency>
    groupId>com.sun.facelets</groupId>
    <artifactId>jsf-facelets</artifactId>
    <version>1.1.14</version>
</dependency>

在pom.xml.

代码中没有faces-config.xml（至少，我找不到）。

当我运行应用程序时，我收到另一个错误：

这个 FaceletViewHandler 在哪里使用？

这是更新的代码：https ://dl.dropbox.com/u/11776689/2012_09_29_primefaces_app2.zip

解决方案：

1）备份项目。

2）在 Maven 中重新创建它，如http://myfaces.apache.org/build-tools/archetypes/myfaces-archetype-helloworld20/index.html中所述

  1. 运行命令mvn archetype:generate -DarchetypeCatalog=http://myfaces.apache.org和
  2. myfaces-archetype-helloworld20从可用选项列表中进行选择。

3) 将 PrimeFaces 存储库和依赖项添加到pom.xml.

com.sun.facelets.*堆栈跟踪中的 存在表明您jsf-facelets在 web 应用程序的运行时类路径中拥有来自 Facelets 1.x 的 JAR 文件（并且您已ViewHandler在 web 应用程序的faces-config.xml! 中显式注册它）。

这个不对。从 JSF 2.0 开始，Facelets 已经捆绑在 JSF API/impl 库中（已移至com.sun.faces.facelets.*包中）。删除依赖项jsf-facelets及其<view-handler>从faces-config.xml. 一个干净的 JSF 2.0 / Facelets 设置可以只用FacesServletin web.xml（甚至没有上下文参数和所有其他混乱）和一个空的faces-config.xml.

这个异常的原因基本上归结为 Facelets 2.0 兼容的标签库（如 PrimeFaces >=2.0）不能被 Facelets 1.x 识别。

在开始使用 JSF 2.0 时，请确保您没有查看 JSF 1.x 书籍/资源/示例。自 JSF 2.x 以来，很多事情都发生了变化，并且以不同的方式完成。从我们的 JSF wiki 页面开始。
