It's still to be used for many things which can't be annotated. E.g. custom JSF validation messages:

<pre><code>&lt;application&gt;
 &lt;message-bundle&gt;com.example.i18n.messages&lt;/message-bundle&gt;
&lt;/application&gt;
</code></pre>

A global i18n bundle (so that you don't need to declare <code>&lt;f:loadBundle&gt;</code> in every view):

<pre><code>&lt;application&gt;
 &lt;resource-bundle&gt;
 &lt;base-name&gt;com.example.i18n.Text&lt;/base-name&gt;
 &lt;var&gt;text&lt;/var&gt;
 &lt;/resource-bundle&gt;
&lt;/application&gt;
</code></pre>

Explicitly supported i18n locales (so that the not-declared ones will be ignored even though there's a message bundle or resource bundle for it):

<pre><code>&lt;application&gt;
 &lt;locale-config&gt;
 &lt;default-locale&gt;en&lt;/default-locale&gt;
 &lt;supported-locale&gt;nl&lt;/supported-locale&gt;
 &lt;supported-locale&gt;es&lt;/supported-locale&gt; 
 &lt;supported-locale&gt;de&lt;/supported-locale&gt; 
 &lt;/locale-config&gt;
&lt;/application&gt;
</code></pre>

Custom <a href="http://download.oracle.com/javaee/6/api/javax/faces/application/ViewHandler.html">view handlers</a>:

<pre><code>&lt;application&gt;
 &lt;view-handler&gt;com.example.SomeViewHandler&lt;/view-handler&gt;
&lt;/application&gt;
</code></pre>

<a href="http://download.oracle.com/javaee/6/api/javax/faces/event/PhaseListener.html">Phase listeners</a> (there's still no annotation for that):

<pre><code>&lt;lifecycle&gt;
 &lt;phase-listener&gt;com.example.SomePhaseListener&lt;/phase-listener&gt;
&lt;/lifecycle&gt;
</code></pre>

Managed beans which can't be annotated (the below one gives current <code>Date</code> on <code>#{now}</code>):

<pre><code>&lt;managed-bean&gt;
 &lt;description&gt;Current date and time&lt;/description&gt;
 &lt;managed-bean-name&gt;now&lt;/managed-bean-name&gt;
 &lt;managed-bean-class&gt;java.util.Date&lt;/managed-bean-class&gt;
 &lt;managed-bean-scope&gt;request&lt;/managed-bean-scope&gt;
&lt;/managed-bean&gt;
</code></pre>

Custom factories, such as custom exception handler factory (it also allows factories for <a href="http://download.oracle.com/javaee/6/api/javax/faces/context/FacesContext.html"><code>FacesContext</code></a>, <a href="http://download.oracle.com/javaee/6/api/javax/faces/context/ExternalContext.html"><code>ExternalContext</code></a>, <a href="http://download.oracle.com/javaee/6/api/javax/faces/lifecycle/Lifecycle.html"><code>LifeCycle</code></a> and many more so that you can provide your custom implementation):

<pre><code>&lt;factory&gt;
 &lt;exception-handler-factory&gt;com.example.SomeExceptionHandlerFactory&lt;/exception-handler-factory&gt;
&lt;/factory&gt;
</code></pre>

To name only the commonly used ones. If you have <code>faces-config.xml</code> tag autocompletion in your IDE, you can find them all out. Only the managed beans, validators, converters, components, renderers and point-to-point navigation cases are not needed anymore thanks to the new annotations and implicit navigation.

After the JSF 2 big support for annotations, I'm wondering what I would use the <code>faces-config.xml</code> for. What is its importance now?

In other words, what are the configurations that can only be done through <code>faces-config.xml</code> and not via annotations?

Right now all what I am using it for is to declare Spring's EL resolver.

<pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;faces-config
 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-facesconfig_2_0.xsd"
 version="2.0"&gt;

 &lt;application&gt;
 &lt;el-resolver&gt;
 org.springframework.web.jsf.el.SpringBeanFacesELResolver
 &lt;/el-resolver&gt;
 &lt;/application&gt; 
&lt;/faces-config&gt;
</code></pre>

What is the use of faces-config.xml in JSF 2?

在JSF2对注解有了很大的支持之后，我想知道我要用faces-config.xml做什么。它现在的重要性是什么？换句话说，什么是只能通过faces-config.xml而不能通过注释完成的配置？现在，我使用它的目的是声明Spring的EL解析器。<?xml version="1.0" encoding="UTF-8"?...
