Multiple json calls - fullcalendar

Question

I can retrieve resources but I can't do the same with it's events.
$(document).ready(function() {
...
defaultView: 'resourceDay',
resources: 'LDAPRetornarSalesEdifici?edifici=' + $('#edifici').val(),
events: 'SQLRetornarHorariEdificiJSON?edifici=' + $('#edifici').val(),
viewRender: function(view, element) {
$("#calendar").fullCalendar('refetchEvents');
}
...
Both LDAPRetornarSalesEdifici and SQLRetornarSalesEdifici are servlets. The first one load my resources (meeting rooms) and the second one doesn't work.
This is the output of LDAPRetornarSalesEdifici:
[{"id":"3PB.C21","name":"Aula Félix Serratosa"},{"id":"3PB.C31","name":"Terrassa Administració"}]
This is the output of SQLRetornarSalesEdifici:
[{"id":"65985","title":"Seminari Dep. Quimica-NO ES FA (Eva Poca) - Seminari Quimica","start": {"year":2014,"month":9,"dayOfMonth":30,"hourOfDay":9,"minute":30,"second":0},"end":{"year":2014,"month":9,"dayOfMonth":30,"hourOfDay":10,"minute":30,"second":0},"allDay":false,"url":"ReservaModificarMostrarResultat?id\u003d65985","resourceId":"3PB.C21"},{"id":"63098","title":"Programa Oncologia (Cristina Méndez) - Seminari","start":{"year":2014,"month":9,"dayOfMonth":30,"hourOfDay":15,"minute":30,"second":0},"end":{"year":2014,"month":9,"dayOfMonth":30,"hourOfDay":17,"minute":30,"second":0},"allDay":false,"url":"ReservaModificarMostrarResultat?id\u003d63098","resourceId":"3PB.C21"}]
