I don't think you need to create this class yet. Better leave it for when you will start working on the chat module. All you need to do for this task is to send the events, not receive them. When you will need to write the listener, it won't be in the org.xwiki.observation.event package, but in your own package (something like org.xwiki.chat.events.UserLoginListener). > 2.

But as Asiri said, you will probably get this as an automatic dependency injection, and not using the component manager. > 3.

If you will write your listener as a component, there is a special interface that components can implement, Initializable, which adds an initialize() method which will be called when the component is created and all its dependencies are in place. > 6.

This will be refined later, since users that have cookies use a different mechanism. But LoginSubmitAction is a pretty good initial approximation. > 7.

Only steps 3 and 6 should be implemented now. -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
