<div class="sectionbody">
<div class="paragraph">
<p>When your beans are annotated with a scope type, the server recognizes
the application as a bean archive and no additional configuration is
required. The possible scope types for CDI beans are listed in
<a href="cdi-basic008.html#GJBBK">Using Scopes</a>.</p>
</div>
<div class="paragraph">
<p>CDI uses an optional deployment descriptor named <code>beans.xml</code>. Like other
Java EE deployment descriptors, the configuration settings in
<code>beans.xml</code> are used in addition to annotation settings in CDI classes.
The settings in <code>beans.xml</code> override the annotation settings if there is
a conflict. An archive must contain the <code>beans.xml</code> deployment
descriptor only in certain limited situations, described in
<a href="cdi-adv.html#GJEHI">Chapter 27, "Contexts and Dependency Injection
for Java EE: Advanced Topics"</a>.</p>
</div>
<div class="paragraph">
<p>For a web application, the <code>beans.xml</code> deployment descriptor, if
present, must be in the <code>WEB-INF</code> directory. For EJB modules or JAR
files, the <code>beans.xml</code> deployment descriptor, if present, must be in the
<code>META-INF</code> directory.</p>
