    copied!<p>If the origin is XML, I suggest to go for a completely different approach: <a href="http://www.w3schools.com/xml/xsl_intro.asp" rel="nofollow noreferrer">XSL</a>. Facelets is XHTML based. You can easily use XSL to go from XML to XHTML. This is doable with a bit decent <code>Filter</code> which kicks in before JSF is doing the works.</p> <p>Here's a kickoff example.</p> <p><code>persons.xml</code></p> <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;persons&gt; &lt;person&gt; &lt;name&gt;one&lt;/name&gt; &lt;age&gt;1&lt;/age&gt; &lt;/person&gt; &lt;person&gt; &lt;name&gt;two&lt;/name&gt; &lt;age&gt;2&lt;/age&gt; &lt;/person&gt; &lt;person&gt; &lt;name&gt;three&lt;/name&gt; &lt;age&gt;3&lt;/age&gt; &lt;/person&gt; &lt;/persons&gt; </code></pre> <p><code>persons.xsl</code></p> <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"&gt; &lt;xsl:output method="xml" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/&gt; &lt;xsl:template match="persons"&gt; &lt;html&gt; &lt;f:view&gt; &lt;head&gt;&lt;title&gt;Persons&lt;/title&gt;&lt;/head&gt; &lt;body&gt; &lt;h:panelGrid columns="2"&gt; &lt;xsl:for-each select="person"&gt; &lt;xsl:variable name="name"&gt;&lt;xsl:value-of select="name" /&gt;&lt;/xsl:variable&gt; &lt;xsl:variable name="age"&gt;&lt;xsl:value-of select="age" /&gt;&lt;/xsl:variable&gt; &lt;h:outputText value="{$name}" /&gt; &lt;h:outputText value="{$age}" /&gt; &lt;/xsl:for-each&gt; &lt;/h:panelGrid&gt; &lt;/body&gt; &lt;/f:view&gt; &lt;/html&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p><code>JsfXmlFilter</code> which is mapped on <code>&lt;servlet-name&gt;</code> of the <code>FacesServlet</code> and assumes that the <code>FacesServlet</code> itself is mapped on an <code>&lt;url-pattern&gt;</code> of <code>*.jsf</code>.</p> <pre><code>public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletRequest r = (HttpServletRequest) request; String rootPath = r.getSession().getServletContext().getRealPath("/"); String uri = r.getRequestURI(); String xhtmlFileName = uri.substring(uri.lastIndexOf("/")).replaceAll("jsf$", "xhtml"); // Change this if FacesServlet is not mapped on `*.jsf`. File xhtmlFile = new File(rootPath, xhtmlFileName); if (!xhtmlFile.exists()) { // Do your caching job. String xmlFileName = xhtmlFileName.replaceAll("xhtml$", "xml"); String xslFileName = xhtmlFileName.replaceAll("xhtml$", "xsl"); File xmlFile = new File(rootPath, xmlFileName); File xslFile = new File(rootPath, xslFileName); Source xmlSource = new StreamSource(xmlFile); Source xslSource = new StreamSource(xslFile); Result xhtmlResult = new StreamResult(xhtmlFile); try { Transformer transformer = TransformerFactory.newInstance().newTransformer(xslSource); transformer.transform(xmlSource, xhtmlResult); } catch (TransformerException e) { throw new RuntimeException("Transforming failed.", e); } } chain.doFilter(request, response); } </code></pre> <p>Run by <a href="http://example.com/context/persons.jsf" rel="nofollow noreferrer">http://example.com/context/persons.jsf</a> and this filter will kick in and transform <code>persons.xml</code> to <code>persons.xhtml</code> using <code>persons.xsl</code> and finally put <code>persons.xhtml</code> there where JSF expect it is.</p> <p>True, XSL has a bit of learning curve, but it's IMO the right tool for the job since the source is XML and destination is XML based as wel.</p> <p>To do the mapping between the form and the managed bean, just use a <code>Map&lt;String, Object&gt;</code>. If you name the input fields like so</p> <pre class="lang-xml prettyprint-override"><code>&lt;h:inputText value="#{bean.map.field1}" /&gt; &lt;h:inputText value="#{bean.map.field2}" /&gt; &lt;h:inputText value="#{bean.map.field3}" /&gt; ... </code></pre> <p>The submitted values will be available by <code>Map</code> keys <code>field1</code>, <code>field2</code>, <code>field3</code>, etc.</p>
