Custom Event trigger not working from SDK

Hi

I need to trigger a custom event from SDK. Below Code executes successfully but the trigger is not working.

I scheduled a webi report based on this customer event.  When I trigger the event from CMC, report runs but when I execute below code, it doesn't.  Could you please help.

   String query = "SELECT * FROM CI_SYSTEMOBJECTS WHERE SI_KIND='Event' and SI_NAME='New_Event'";

            IInfoObjects lInfoObjects = objInfoStore.query(query);

            IUserEvent cEvent = (IUserEvent)lInfoObjects.get(0);

            cEvent.trigger();                

            cEvent.save();                                 

            objInfoStore.commit(lInfoObjects);

Also, Do we have RESTful Webservice to trigger events. If so, could you please give the code.

Thanks
