在 RichFaces 中，为了上传我使用的文件rich:fileUpload。通过使用rich:fileUpload添加、上传和清除所有按钮会在richfaces liveemo 示例中自动生成，但对我来说，添加、上传和清除所有按钮在我的浏览器中显示为文本，我应该在哪里更改以便添加、上传和清除所有可以点击。我是否必须更改web.xml/pom.xml文件中的任何设置。
我正在使用 RichFaces 4 和 JSF 2。
这是我的 web.xml ：

嗨，我现在可以通过简单地提供 h:head 和 h:body 标签来正确获取这些添加和更新按钮，但是我得到了这个异常 javax.faces.event.AbortProcessingException 并且文件没有被上传，如提供的示例中所示链接“文件上传示例”。任何人都可以帮助我解决这个问题
这是我的 xhtml 页面

非常感谢。现在这个错误对我来说已经消失了。我在 web.xml 中将 createTemp 文件设置为 true，但我无法在本地系统的 temp 文件夹中找到上传的文件。也可以通过更改任何文件将上传的文件存储到本地系统中的所需位置web.xml 文件中的设置？请帮助解决这两个问题。
