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

Error Could not find Factory: javax.faces.context.FacesContextFactory

提问by J?cob

I am trying to run a sample primefaces 3.1 application using eclipse. When I run I am getting the following exception. I have placed jstl-1.0.2.jar,jsf-impl-2.0.3.jar,jsf-api-2.0.3.jar,primefaces-3.1.jar under WEb-INF/lib folder and index.jsf is placed under /WebContent.

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。我已经把jstl-1.0.2.jar,jsf-impl-2.0.3.jar,jsf-api-2.0.3.jar,primefaces-3.1.jar放在WEB-INF/lib文件夹下，index.jsf放在/网页内容。

Problem accessing /TestPrime/index.jsf. Reason: 

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

It's Jetty's fault. It is somehow not executing the JSF ConfigureListenerwhich is been registered in the JSF TLD file.

是杰蒂的错。它以某种方式不执行ConfigureListener在 JSF TLD 文件中注册的 JSF。

Add the following entry to your webapp's web.xmlto manually register it:

将以下条目添加到您的 webappweb.xml以手动注册它：

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