[Building Sakai] How difficult is to implement event registering for other tools?

[Stephen Swinsburg]

Hi Luiz,

An event is just a notification that someone did something somewhere.  
If you have a tool that you want to register events into the Sakai  
Event table, then you just need to inject the EventTrackingService  
like this:
private EventTrackingService eventTrackingService;
public void setEventTrackingService(EventTrackingService  
eventTrackingService) {
	this.eventTrackingService = eventTrackingService;
}

then have a method in your API/IMPL (lets call it someLogic) that  
post's the event:
public void postEvent(String event,String reference,boolean modify) {
	 
eventTrackingService 
.post(eventTrackingService.newEvent(event,reference,modify));
}

then in your tool, when appropriate, ie after said event has just  
occurred, post the event:

someLogic.postEvent("my.tool.event", "whereverTheEventOccurred", true);
				
true for modify type events, ie if something was changed, false for  
just viewing/accessing something.

cheers,
Steve
