[Springframework-developer] application event multicaster

[Keith D. <kei...@in...>]

I have a need to inject a handle to an application context's 
application event multicaster for the purpose of wiring up 
application listeners that are instantiated post-startup -- 
programatically -- within my application.  I need this to 
happen automagically, e.g where the user doesn't have to 
remember to do this.  What's the best way to achieve this?  
The best I can come up with is to require manual 
instantation of an ApplicationEventMulticaster bean in the 
context, and inject it automatically using a 
BeanPostProcessor (e.g ApplicationEventMulticasterAware).  
Is there anyway to get a handle to the default multicaster 
associated with an ApplicationContext after the application 
has started?
 
I've considered just having the container instantiate the 
ApplicationListener objects in question, but I really want 
control over the instantation process--I have to make sure 
these objects are prototypes, and I'm slightly concerned 
about users forgetting to mark them 'singleton=false' within 
the context.. this option is not out, but I am preferring 
using another object as the "container / factory" for the 
prototypes it produces to simplify what the user has to 
configure... (it's the view descriptor / view case I emailed 
on earlier --> view descriptors produce view instances, 
views are prototypes and typically are application event 
listeners...)
 
Thanks,
Keith
