using curl to post ical calendars

**rdavison** · 01-24-2007, 11:47 AM

Hi all,

I'm a little new to all of this, but have so far managed to get Zimbra up and running and my company is very impressed with the features!

I've tried some calendar migration with some users, and it seems ok for two of them, but when trying myself I run:

curl -u rdavison:mypassword --data-binary @/opt/zimbra/calendar_migrate/rdavison.ics http://zimbratest/zimbra/home/rdavison/calendar?fmt=ics

and get:

HTTP Status 500 - </h1><HR size="1" noshade="noshade">type Exception reportmessage description The server encountered an internal error () that prevented it from fulfilling this request.exception <pre>java.lang.NullPointerException
com.zimbra.cs.mailbox.calendar.ParsedDateTime.add( ParsedDateTime.java:263)

javax.servlet.http.HttpServlet.service(HttpServlet .java:802)
com.zimbra.webClient.filters.SetHeaderFilter.doFil ter(SetHeaderFilter.java:288)

It seems to import calendar entries up until a point. The first one it can't manage is:

BEGIN:VEVENT
UID:HTTPS:-MYCOMPANY-COM-WEBCALENDAR-RDAVISON-0000012782
SUMMARY:Holiday
DESCRIPTION:Holiday
CLASS:PUBLIC
STATUS:CONFIRMED
DTSTART;VALUE=DATETIME:20060904T000000
DTSTAMP:20070124T184351Z
RRULE:FREQ=DAILY;BYDAY=MO,TU,WE,TH,FR;UNTIL=200609 15T230000Z
END:VEVENT

I've exported my original calendar in ical format. Does Zimbra not agree with one of the recurrance rules, or am I doing something obviously wrong??

thanks for any help in advance.

Hi, the NullPointerException is due to a missing null check in the server. That's a bug.

However, your .ics is invalid. It has neither DTEND nor DURATION. One or the other is required according to RFC2445. Even if server is fixed to do the null check properly, your meeting will be treated as having no duration and probably won't show up in the calendar view. Is it possible to fix the source system to regenerate the .ics, then re-import into ZCS?

Thanks for your prompt reply. We use the open source 'webcalendar' so I'll see if there are any known issues with that.

Thanks

Hello.

Just tried the same with an iCal export from GroupOffice :

Code:

$ curl -u sylvain@network-studio.com --data-binary @./david.ics http://localhost/service/home/sylvain@network-studio.com/calendar?fmt=ics
Enter host password for user 'sylvain@network-studio.com':

Line 29 is

Code:

DTSTART;TZID=Fran&amp;ccedil;ais:20070125T140000

I suppose the TZID is wrong ?

Edit a couple of minutes later
I modified the .ics file manually and put CET as TZID (in lines 7 and 29) and it works flawlessly.

Looks like a GroupOffice bug (double encoding the "ç").

That's correct, the TZID was wrong. A TZID value cannot contain double-quote, ";", ":", or ",".
