Hello,
Please let me try to summarize what you are trying to do:
[1] Retrieve an entry from the Google Calendar API.
[2] Copy this entry to another instance and modify its start and end time.
[3] Send a PATCH request to modify the event.
If this is correct, this is what you should do instead:
[1] Retrieve the entry from the Google Calendar API using the entry's self
or edit link instead of the Atom ID.
CalendarEventEntry entry = myService.getEntry(new URL("<entry's self
or edit link"), CalendarEventEntry.class);
[2] Modify the event without having to create another instance of the
object.
entry.getTimes().get(0).setStartTime(DateTime.parseRfc822("<RFC833
start time>"));
entry.getTimes().get(0).setEndTime(DateTime.parseRfc822("<RFC833 start
time>"));
[3] Send an
UPDATE<http://code.google.com/apis/calendar/data/2.0/developers_guide_java.html#UpdatingEvents>request
to the API using the updated event and the event's self or edit
link.
CalendarEventEntry updatedEntry =
myService.update(new URL(entry.getEditLink().getHref()), entry);
If you still want to use a PATCH request instead of an UPDATE request.
please refer to the "Making a partial
update<http://code.google.com/apis/calendar/data/2.0/developers_guide_java.html#PartialUpdate>"
section of the Java developer's guide.
Best,
Alain
