    copied!<p>By the way.. you can avoid implementing your own resource resolver when you're using seam solder (currently being integrated into apache deltaspike) which is a really useful library complementing CDI (your typical Java EE 6 component model)</p> <p>I too experimented with modularity in jsf applications. Basically I built a template interface with a toolbar which gets filled with buttons provided by each module. Typically you will do this by providing a List of Strings as a Named Object:</p> <pre><code>@Produces @SomethingScoped @Named("topMenuItems") public List&lt;String&gt; getTopMenuItems(){ return Arrays.asList("/button1.xhtml", "/button2.xhtml", "/button3.xhtml"); } </code></pre> <p>Notice how each of the buttons may come from a different module of the jsf application. The template interface contains a panel where </p> <p>you can use it in your markup the following way (at your own risk ;) ) :</p> <pre><code>.... xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:ui="http://java.sun.com/jsf/facelets" .... &lt;xy:toolbar&gt; &lt;xy:toolbarGroup&gt; &lt;c:forEach items="#{topMenuItems}" var="link"&gt; &lt;ui:include src="#{link}" /&gt; &lt;/c:forEach&gt; &lt;/xy:toolbarGroup&gt; &lt;/xy:toolbar&gt; &lt;xy:panel&gt; &lt;ui:include src="#{contentPath}"/&gt; &lt;/xy:panel&gt; </code></pre> <p>This was the toolbar and the content panel. </p> <p>a simple button or view definition may look like this: </p> <pre><code>&lt;ui:composition ...&gt; &lt;xy:commandButton actionListener="#{topMenuController.switchContent()}" value="Test" id="testbutton" /&gt; &lt;/ui:composition&gt; </code></pre> <p>lets name this artifact view1.xhtml</p> <p>When this button is pushed (which doesn't trigger a postback using the actionListener, we want to reload the content using ajax) the switchContentMethod in your controller may change the string returned by getContentPath : </p> <pre><code>public void switchContent(){ contentPath = "/view1.xhtml"; } @Produces @SomethingScoped @Named("contentPath") public String getContentPath(){ return contentPath; } </code></pre> <p>now you can change the view displayed in the panel using the button in the menubar which sort of gives you navigation without page reloads.</p> <p><strong>Some advice ( or 'what I've learned' ) :</strong> </p> <ol> <li>You may wanna choose a large scope for the getTopMenuItems method</li> <li>Don't nest the ui:include tag. Unfortunately this is not possible (e.g. your view1.xhtml cannot include another composition). I really would like something like this to be possible as you can build really modular jsf views with this, kinda like portlets only without the portlets.. =D </li> <li>doing ui:include in container components like tabviews also proves problematic. </li> <li>generally it's not advisable to mix JSTL (c:forEach) and JSF. Still I found this to be the only way working as ui:repeat gets evaluated <em>too late</em> e.g. your included content does not appear.</li> </ol>
