Application was not properly initialized at startup, could not find Factory:

我刚开始接触jsf，写了第一个jsf代码如下：

<f:view>
        <h:inputText id="name"></h:inputText>
    </f:view>运行一下，出现了Application was not properly initialized at startup, could not find Factory:这个错误，搞了半天是web.xml文件配置上要加上以下代码：

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