在RichFaces中，为了上传我使用的文件rich:fileUpload。通过使用rich:fileUpload添加，上传和全部清除按钮会自动在richfaces livedemo示例中生成，但对于我来说，添加，上传和全部清除在我的浏览器中显示为文本，我应该在哪里更改以便添加，上载和clearAll可以点击。我必须更改web.xml/pom.xml文件中的任何设置。使用RichFaces上传文件
我使用RichFaces的4和JSF 2
这是我的web.xml：

嗨，我得到这些添加和更新按钮现在正确地通过简单地提供h：head和h：body标签，但我得到这个异常javax.faces.event.AbortProcessingException并且文件没有被上传，如链接“FileUpload example”中提供的示例所示。能够帮助我解决这个问题的任何人
这是我的XHTML页面

感谢lot.Now的错误是走了我。 我在web.xml中将createTemp文件设置为true，但是我无法在本地系统的temp文件夹中找到上传的文件。还有可能通过更改上传的文件到本地系统中的所需位置web.xml文件中的任何设置？ 请帮助解决这两个问题。
什么Richfaces版本/ JSF版本和你的web.xml在哪里？ – kolossus
你可以发布你的视图代码（rich：fileUpload）和你的bean代码吗？ –
