 /**
 22  
  * This is an implementation of the ObjectFactory interface which simply delegates to 
 23  
  * the Spring ApplicationContext.  Since the delegation happens each time a call to 
 24  
  * getOrCreate() is made, this will correctly handle Spring beans which are 
 25  
  * non-singletons (factory beans, etc.)
 26  
  * 
 27  
  * Singleton usage:
 28  
  * 
 29  
  *   <model>
 30  
  *       <service name="myOrangeService">
 31  
  *           <service>
 32  
  *               <spring-object bean="myBean"/>
 33  
  *           </service>
 34  
  *       </service>
 35  
  *   </model>
 36  
  *
 37  
  *   <spring:bean id="myBean" class="com.foo.Bar"/>
 38  
  *   
 39  
  * Non-singleton usage:
 40  
  * 
 41  
  *   <model>
 42  
  *       <service name="myOrangeService">
 43  
  *           <service>
 44  
  *               <spring-object bean="myFactoryBean"/>
 45
