Save Entries into database

[VarletNicolas]

Hello everybody,

I do not understand how I can save the data. Could you help me by giving me examples. It's not for lack of trying but I'm blocking for too long. (I do not understand how to use your event and / or do not know how to recover the data.).
Even though I read the other two post on the same topic it does not really help me.

My goal is to store either the calendar or any entries
in database via a LongBlob.

Everything is programmed except the system for saving entries.

I hope I have been sure, if not, do not hesitate.

Thank you for your help.

birthdays = new Calendar("Anniversaire");
birthdays.setStyle(Style.STYLE1);
myCalendarSource.getCalendars().addAll(birthdays, ...);

 EventHandler<CalendarEvent> l = e -> handleEvent1(e);
 birthdays.addEventHandler(l);

private EventHandler<CalendarEvent> handleEvent1(CalendarEvent e) {

// to get entry
e.getEntry();
