First you need to have facelets configured.

After that, I would do this:


<?xml version="1.0" encoding="UTF-8" ?>
<f:view xmlns="http://www.w3.org/1999/xhtml"
	xmlns:ui="http://java.sun.com/jsf/facelets"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:tr="http://myfaces.apache.org/trinidad"
	xmlns:f="http://java.sun.com/jsf/core">

	<tr:document mode="default" title="Test Form">
		<tr:form id="my_form" usesUpload="true">
                       ...<your stuff here>...
		</tr:form>
	</tr:document>
</f:view>

if this doesn't work, I suggest you to check your faces configurations 
and web.xml
