/**
 * This interface is implemented by factory components which provide
 * instances to the flex messaging framework.  To configure flex data services
 * to use this factory, add the following lines to your services-config.xml
 * file (located in the WEB-INF/flex directory of your web application).
 *
 *	<factories>
 *     <factory id="spring" class="flex.samples.factories.SpringFactory" />
 *  </factories>
 *
 * You also must configure the web application to use spring and must copy the spring.jar
 * file into your WEB-INF/lib directory.  To configure your app server to use spring,
 * you add the following lines to your WEB-INF/web.xml file:
 *
 *   <context-param>
 *        <param-name>contextConfigLocation</param-name>
 *        <param-value>/WEB-INF/applicationContext.xml</param-value>
 *   </context-param>
 *
 *   <listener>
 *       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 *   </listener>
 * 
 * Then you put your spring bean configuration in WEB-INF/applicationContext.xml (as per the
 * line above).  For example:
 * 
 *  <?xml version="1.0" encoding="UTF-8"?>
 *  <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
 *   
 *  <beans>
 *    <bean name="weatherBean" class="dev.weather.WeatherService" singleton="true"/>
 *  </beans>
 *  
 * Now you are ready to define a destination in flex that maps to this existing service. 
 * To do this you'd add this to your WEB-INF/flex/remoting-config.xml:
 *
 *  <destination id="WeatherService">
 *      <properties>
 *          <factory>spring</factory>
 *          <source>weatherBean</source>
 *      </properties>
 *  </destination>
