Question

我正在尝试制作一个简单的JSF（基于PrimeFaces）应用程序运行。

主页非常简单：

<?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

尝试使用mvn jetty:run和
在浏览器中打开页面

我收到以下错误：

如何解决此错误？

更新1：

根据BalusC的建议，我注释掉了依赖

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

pom.xml

。

代码中没有faces-config.xml（至少，我找不到它）。

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？

以下是更新后的代码：https://dl.dropbox.com/u/11776689/2012_09_29_primefaces_app2.zip

解决方案：

1）备份项目。

2）按照http://myfaces.apache.org/build-tools/archetypes/myfaces-archetype-helloworld20/index.html由

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

3）将PrimeFaces存储库和依赖项添加到pom.xml。

Answer 1

堆栈跟踪中com.sun.facelets.*的存在告诉您在webapp的运行时类路径中有来自Facelets 1.x的jsf-facelets JAR文件（并且您已明确注册其ViewHandler在webapp的faces-config.xml中！）。

这是不对的。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）。 从jsf-facelets移除 <view-handler>依赖关系及其faces-config.xml。可以使用 FacesServlet中的web.xml创建一个干净的JSF 2.0 / Facelets设置（甚至没有上下文参数和所有其他混乱）和空faces-config.xml。

此异常的原因基本上归结为Facelets 1.x无法识别Facelets 2.0兼容的标记库（如PrimeFaces＆gt; = 2.0）。

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。从JSF 2.x开始，很多东西都被改变了，并且做了不同的事情。 Start at our JSF wiki page
