Singleton EventPublisher/Listener

[zooxmusic]

Hi all, I am building a JSR-296 swing app ontop of a spring backend using remote services. The new BSAF has a pretty nice @Action/Task architecture. My basic question is;

I need, pretty much everywhere, to register as a listener for Task events but my objects are disparate. Meaning I have no easy way to get from the class I want to listen to the task event to register myself as a listener.

What is the suggested way to handle this?

I was toying with a Singleton EventQueue for my application but I do not feel warm and fuzzy about it. I am not sure why I don't feel warm and fuzzy but I don't. Maybe because it reminds me of the WM_* windows message system.


Thanks in advance

You know, after reading a bit on Martin Fowler's site and a few others, I am completely warm and fuzzy about an event architecture. It decouples my code even more. I was actually feeling opposite of how I should have been. I also have found EventBus for swing and non-swing and looks to be pretty robust. If anyone is interested it is located here;

I still wouldn't mind starting a discussion on the pros and cons of this approach.
