extension for WCAP ( Web Calendar Access Protocol). Finally, starting in 2008, the Sun Java System Communications Suite 6 will include an AJAX-based Web client which will provide better "thick client-like" user interactions. A useful feature of Calendar Server is the notification service. This service will send an e-mail or an SMS to the calendar owner. These messages are sent to the calendar owner if he/she has been invited to an appointment or as a reminder of an upcoming appointment. These reminders are directed to a person's cell phone by using their phone carrier's email address assigned to their phone. The notification services are also useful for developers to implement their own software applications. Calendar reminders and change events are published to a

History and use

Sun's Java System Calendar Server has a long history, drawing technology from Sun Internet Calendar Server (SICS) and Netscape Calendar Server (NCS). The software has undergone several name changes; in addition to the above, it has also been marketed as ''iPlanet Calendar Server'' and ''Sun ONE Calendar Server''. The code base has been carried on throughout these name changes with only feature/packaging enhancements and bug fixes. Since 2003, the Calendar Server has been included as part of Sun's Java Enterprise System, a collection of infrastructure software applications and tools. It is also available as part of the Sun Java System Communications Suite, a smaller collection of messaging and collaboration services that includes Sun Java System Messaging Server, Sun Java System Instant Messaging Server, and Sun Java System Communications Express. Supporting server software for the Calendar Server includes Sun Java System Directory Server, Sun Java System Access Manager, and
