 * <ol>
 *   <li>Use dependency injection via spring. Example:

 *       <bean id="myBean" class="com.xyz.MyBean">
 *         <constructor-arg ref="xstreamPersisterFactory"/>
 *       </bean>
 *     </pre>
 *   <li>Lookup via {@link GeoServerExtensions#bean(Class)}:
 *     <pre>
 *       XStreamPersisterFactory xpf = GeoServerExtension.bean(XStreamPeristerFactory.class);
 *     </pre>
