Question

h：inputFile未显示在页面中。这是我的jsf代码

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

      xmlns:h="http://xmlns.jcp.org/jsf/html">



<h:head>


</h:head> 
<h:body>
<h:form>
<h:inputFile></h:inputFile>

</h:form>

</h:body>
</html>

实际上我从

更改了命名空间

<xmlns:h="http://java.sun.com/jsf/html">

至<xmlns:h="http://xmlns.jcp.org/jsf/html">

通过查看论坛中的先前问题，我更改了我的命名空间，但没有显示任何ui组件，包括h：inputfile

我还添加了这些jar文件

jsf-impl-2.2.4
jsf-api-2.2.4

我的web.xml看起来像这样
