    copied!<p>I need to change the context of my site by using parameter sended by client. </p> <p>For example, if I call <code>http://localhost:8084/JSF/</code> I load the usual <code>index.xhtml</code> with the "Homepage" page on the <code>content</code> template (as default). But, if I call <code>http://localhost:8084/JSF/index.xhtml?page=profile</code>, I need a sort of switch in the <code>index.xhtml</code>, and include/insert the profile template (or a page that define profile) in my <code>content</code> area. </p> <p>I think i need to manage a servlet to do it, because i don't think i can create a sort of swith in my index.xhtml. So i think i need to load some template instead of another.</p> <p>Which servlet i need to use? Or i need to create my own Servlet to do this?</p> <p>Cheers</p> <p><strong>UPDATE (added after BalusC's suggestion)</strong></p> <pre><code>package Beans; import javax.faces.bean.ManagedProperty; import javax.faces.bean.ManagedBean; @ManagedBean(name="selector") @ManagedProperty(value="#{param.page}") public class Selector { private String page; public String getPage() { return page; } public void setPage(String page) { this.page = page; } } </code></pre> <p><code>template.xhtml</code></p> <pre><code>&lt;?xml version='1.0' encoding='UTF-8' ?&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html"&gt; &lt;h:head&gt; &lt;title&gt;&lt;ui:insert name="title"&gt;Facelets Template&lt;/ui:insert&gt;&lt;/title&gt; &lt;/h:head&gt; &lt;h:body&gt; &lt;ui:insert name="login_homepage"&gt;Box Content Here&lt;/ui:insert&gt; &lt;ui:insert name="content_homepage"&gt;Box Content Here&lt;/ui:insert&gt; &lt;/h:body&gt; &lt;/html&gt; </code></pre> <p><code>index.xhtml</code></p> <pre><code> &lt;?xml version='1.0' encoding='UTF-8' ?&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;ui:composition template="./template.xhtml" xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"&gt; &lt;ui:define name="title"&gt; // title &lt;/ui:define&gt; &lt;ui:define name="login_homepage"&gt; // login &lt;/ui:define&gt; &lt;ui:include src="#{selector.page}.xhtml" /&gt; &lt;ui:define name="content_homepage"&gt; // content &lt;/ui:define&gt; &lt;/ui:composition&gt; </code></pre> <p><code>web.xml</code></p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"&gt; &lt;context-param&gt; &lt;param-name&gt;javax.faces.PROJECT_STAGE&lt;/param-name&gt; &lt;param-value&gt;Development&lt;/param-value&gt; &lt;/context-param&gt; &lt;servlet&gt; &lt;servlet-name&gt;Faces Servlet&lt;/servlet-name&gt; &lt;servlet-class&gt;javax.faces.webapp.FacesServlet&lt;/servlet-class&gt; &lt;load-on-startup&gt;1&lt;/load-on-startup&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;Faces Servlet&lt;/servlet-name&gt; &lt;url-pattern&gt;/faces/*&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; &lt;session-config&gt; &lt;session-timeout&gt; 30 &lt;/session-timeout&gt; &lt;/session-config&gt; &lt;welcome-file-list&gt; &lt;welcome-file&gt;faces/index.xhtml&lt;/welcome-file&gt; &lt;/welcome-file-list&gt; &lt;/web-app&gt; </code></pre> <p><code>profile.xhtml</code></p> <pre><code>&lt;?xml version='1.0' encoding='UTF-8' ?&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;ui:composition xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets"&gt; &lt;h2&gt;PROFILE&lt;/h2&gt; &lt;/ui:composition&gt; </code></pre>
