<p>To make a bean accessible through the EL, use the <code>@Named</code> built-in qualifier:</p>
</div>
<div class="listingblock">
<div class="content">
<pre class="prettyprint highlight"><code class="language-oac_no_warn" data-lang="oac_no_warn">import javax.enterprise.context.RequestScoped;
import javax.inject.Inject;
import javax.inject.Named;
@Named
@RequestScoped
public class Printer {
@Inject @Informal Greeting greeting;
...
}</code></pre>
</div>
</div>
<div class="paragraph">
<p>The <code>@Named</code> qualifier allows you to access the bean by using the bean
name, with the first letter in lowercase. For example, a Facelets page
would refer to the bean as <code>printer</code>.</p>
</div>
<div class="paragraph">
<p>You can specify an argument to the <code>@Named</code> qualifier to use a
nondefault name:</p>
</div>
<div class="listingblock">
<div class="content">
<pre class="prettyprint highlight"><code class="language-oac_no_warn" data-lang="oac_no_warn">@Named("MyPrinter")</code></pre>

<div class="paragraph">
<p>With this annotation, the Facelets page would refer to the bean as
<code>MyPrinter</code>.</p>
