Note that you don't need to do that explicitly, your java componenet implementing EventListener will be automatically registered (if it's a component). The groovy page has to do it "by hand" because we don't have such mechanism for wiki pages. > > The irc bot which is written entirely in Groovy but it contains a class which > implements EventListener (IRCEventListener) and it has a section which > registers > IRCEventListener with ObservationManager using this: > def listener = new IRCEventListener(bot, xwiki, xcontext) > observation.addListener(listener) > > Best of luck, > > Caleb James DeLisle > > > J.
