Appendix F  
Using Sun ONE Instant Messaging Pop-up Reminders

Sun ONE Calendar Server 5.1.1 (or later) is integrated with Sun ONE Instant Messaging 6.0 (or later) to provide automatic pop-up reminders for both calendar events and tasks on the Instant Messenger desktop.

This appendix describes:

Pop-up Reminders Operation

Pop-up reminders operate based on email reminders. An alarm causes Calendar Server to send an email notification and Instant Messaging to display a pop-up reminder, depending on the options are configured by both the end user and the Calendar Server administrator:

Pop-up Reminders Architectural Flow

If configured, Instant Messaging pop-up reminders follow this architectural flow:

  1. The Instant Messaging JMS subscriber subscribes to Calendar Server events and notifications in the Event Notification Service (ENS).
  2. Calendar Server publishes an event or notification in text/xml or text/calendar format to ENS.
  3. The Instant Messaging JMS subscriber receives the calendar event or notification and then generates a message in text/calendar format.
  4. The Instant Messaging server sends the message to the calendar owner, if the end user is online.
  5. Instant Messenger generates an HTML pop-up reminder on the end user’s desktop based on the message.
