Sun just release an Evolution connector for Sun Java System Calendar Server. For more information on the announcement, see URL.
The connector is also bundled within Sun Java Desktop System. And that was where I got introduced to the connector. All I really had to do to setup the connector was to create an account by specify calendar server host name and port number. After that, I could connect to the server with my user information. The server immediately loaded my calendar, todo list, and any other public calendars that I subscribed. The connector enabled me to view and mangage calendars / todo list with a rich user GUI experience as if I am access the data locally in Evolution when the data actually stored on the server side. IMHO, this is definitely a friendly way to access to my calendar.
For more infomation on how to use the connector in Evolution on Java Desktop System, plase see documentation.
