 <p>The <em>`@LocalClient</em>` annotation (org.apache.openejb.api.LocalClient) is an
 innovation that crosses concepts of an Java EE Application Client with a
 plain Java SE client. This particular annotation is focused on clients
 of an Embeddable EJB container, i.e. local clients. There is another
 annotation in development called <code>@RemoteClient</code> that will be focused on
 remote clients; clients running outside the vm the container runs.</p>
 </div>
 <div class="paragraph">
 <p>Any clients annotated with <code>@LocalClient</code> will be scanned at deployment
 time for usage of injection-related annotations. The references in the
 @LocalClient will be processed with the application just as if the class
 was a Java EE Application Client module, but with a few slight
 differences:</p>

 <p>As well since this is not a heavyweight Java EE Application Client, you
 are not required to use any special packaging or command-line parameters
 to run the client. Your client can be a Unit Test or any plain java code
 that needs to pull objects from the Embedded EJB container. Classes with
 @LocalClient can be placed in a Client module or an EJB module. A given
 module may have as many classes annotated with <code>@LocalClient</code> as it
 wishes.</p>
