[Newbie question] Syncing two remote caldav calendars?

[Tom Vercauteren]

Hi all,

I just discovered caldav4j and had some questions to assess the difficulty of achieving a particular task before actually diving into the code.

I have two calendars that I want to synchronize:

• A google calendar
• A caldav calendar on a remote davical server

I have searched the web for such an existing tool but haven't really found one. Davical has a php script to perform that but it requires a fully running davical instance which I do not have on my local machine:

http://repo.or.cz/w/davical.git/blob/HEAD:/scripts/sync-remote-caldav.php

I was therefore wondering how difficult it would be to write a script with caldav4j that would synchronize the two calendars. I have briefly looked at the example code but didn't find such synchronization example:

http://code.google.com/p/caldav4j/source/browse/#svn%2Ftrunk%2Fsrc%2Fexample%2Forg%2Fosaf%2Fcaldav4j%2Fexample

Thank you for any advice you might have,

Tom

P.S.: Davical also has a "remote bind" feature but it requires admin rights on the remote davical server which I do not have:

Synching is a complex stuff. You can look at the Funambol Caldav
Connector to learn about sync implementation.

If your servers both support caldav, you may treat them as file
synching. It won't merge events!

Le me know + Peace,

Hi Roberto.

Could you please check the link http://sourceforge.net/projects/funambol-caldav/

It seems like it is not active.

I am working on optimization of sync part by implementing cache.

Could you help me with your views on this.

Regards

I'm there and I can see everything.

funambol-caldav uses EHCache, so you can check how it works there. But
it's not an Android project and uses Java SDK 1.6

Peace,
