If you need an events dispatching system, you may want to take a look at
guts-events (http://kenai.com/projects/guts) which is an Event Bus
system based on Guice.
Or you may take a look at guts-events and get some inspiration from
there and adapt it to your own system ;-)

Hello list,
Inspired by the neat configuration Module for guice persist, I decided
to make something similar for a small subpart of my project. I'm not
fully sure how to create it though.
I want to create a module which sets up the relationship between
listeners and dispatchers in an event system. The event system is
based on a class called ListenerDispatcher<T> [1]. I want the module
to work something like this:
protected void configureEvents() {
connect(ListeningInterface.class,
ClassImplementingListeningInterface.class);
// .... and so on
}
protected void configure() {
configureEvents();
}
What I want that line to do is:
ListenerDispatcher<ListeningInterface> listenerDispatcher =
ListenerDispatcher.create(ListeningInterface.class);
listenerDispatcher.addListener(classImplementingListeningInterface);
Initially I wouldn't need to be able to configure the scope of the
binding. I just want to reduce the boiler plate to that single line
(compared to a lot of configuration atm). My initial thoughts is that
I store all the connect bindings in a map or similar until the
configure() method of AbstractModule is run. In configure I bind/
create all the ListenerDispatchers. So far it's fine, I'm not just
sure how to runt the addListener part.
Thanks for any pointers or help!
