osgi: question about bundle communication / design

hi,

i'm building an application which can send events (with EventAdmin from apache felix), thats the GUI part (eg. "event/buttonXYZ"), so the listeners know when the user hits something in the gui that they should react, or not.
The problem is now that i dont know how many listeners i will have that listen to my main application (they are dynamic), so i have to tell the bundles(plugins) somehow to register itself with the EventHandler

can someone tell me whats the best practice in doing so?

You should consider using Aries or Spring to register your service is the OSGi Service Admin Service. In my opinion, it is more straight-forward than putting in your classes.

bundleContext.registerService(EventHandler.class.getName(), new TheDynamicPlugin() , properties);
