错误找不到工厂：javax.faces.context.FacesContextFactory

Question

我正在尝试使用 eclipse 运行示例 primefaces 3.1 应用程序。当我运行时，我收到以下异常。我已将 jstl-1.0.2.jar、jsf-impl-2.0.3.jar、jsf-api-2.0.3.jar、primefaces-3.1.jar 放置在 WEb-INF/lib 文件夹下，index.jsf 放置在/网络内容。

Problem accessing /TestPrime/index.jsf. Reason: 

    java.lang.IllegalStateException: Application was not properly initialized at startup, could not find Factory: javax.faces.context.FacesContextFactory

这是杰蒂的错。它不知何故没有执行在 JSF TLD 文件中注册的 JSF ConfigureListener 。

将以下条目添加到您的 web 应用程序的 web.xml 中以手动注册它：

<listener>
    <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>
