    copied!<p>Nice idea. This is not supported by the JSF API, but it's in theory possible with a custom script renderer. I played somewhat around it and it's indeed possible. Just create a <code>MultiScriptRenderer</code> which <code>extends ScriptRenderer</code> and override <a href="http://download.oracle.com/javaee/6/api/javax/faces/render/Renderer.html#encodeEnd%28javax.faces.context.FacesContext,%20javax.faces.component.UIComponent%29" rel="nofollow"><code>encodeEnd()</code></a> to check if the <code>name</code> attribute contains the <code>*</code> wildcard and then handle accordingly by scanning for files matching this pattern in the resources folder.</p> <p>Here's a kickoff example:</p> <pre><code>package com.example; import java.io.File; import java.io.FileFilter; import java.io.IOException; import java.util.Map; import javax.faces.component.UIComponent; import javax.faces.context.FacesContext; import com.sun.faces.renderkit.html_basic.ScriptRenderer; public class MultiScriptRenderer extends ScriptRenderer { @Override public void encodeEnd(FacesContext context, UIComponent component) throws IOException { Map&lt;String, Object&gt; attributes = component.getAttributes(); String name = (String) attributes.get("name"); if (name.contains("*")) { String pattern = name.replace(".", "\\.").replace("*", ".*"); String library = (String) attributes.get("library"); File root = new File(context.getExternalContext().getRealPath("/resources/" + (library != null ? library : ""))); for (File file : root.listFiles()) { if (file.getName().matches(pattern)) { attributes.put("name", file.getName()); super.encodeEnd(context, component); } } attributes.put("name", name); // Put original name back. You never know. } else { super.encodeEnd(context, component); } } } </code></pre> <p>Register it in <code>faces-config.xml</code> as follows <em>(Sorry, <a href="http://download.oracle.com/javaee/6/api/javax/faces/render/FacesRenderer.html" rel="nofollow"><code>@FacesRenderer</code></a> annotation isn't going to work until it's fixed in JSF 2.2 for this specific corner case, see also <a href="http://java.net/jira/browse/JAVASERVERFACES-1748" rel="nofollow">JSF issue 1748</a>)</em>:</p> <pre><code>&lt;render-kit&gt; &lt;renderer&gt; &lt;component-family&gt;javax.faces.Output&lt;/component-family&gt; &lt;renderer-type&gt;javax.faces.resource.Script&lt;/renderer-type&gt; &lt;renderer-class&gt;com.example.MultiScriptRenderer&lt;/renderer-class&gt; &lt;/renderer&gt; &lt;/render-kit&gt; </code></pre> <p>Works fine on Mojarra 2.0.3 here. You can use patterns like <code>*.js</code> and <code>prefix*.js</code>. The particular code example is only tight coupled to a specific JSF implementation to save code boilerplate. It also requires that the WAR is expanded on deploy, otherwise browsing the directory by <code>File#listFiles()</code> won't be possible (which thus excludes certain (older) servletcontainer versions/configurations). For other JSF implementations you'll have to extend its <code>ScriptRenderer</code> instead, or write a whole new one if you want to be implementation independent (which should be pretty simple though, just look at standard <code>ScriptRenderer</code> source if you stucks).</p>
